Where to stay in Istanbul
Sultanahmet
The historic peninsula, where Hagia Sophia, the Blue Mosque and Topkapı Palace stand within a ten-minute walk of each other. Perfect for first-timers who want to step out of the hotel straight into the sights, though restaurants cater mostly to tourists and the area goes quiet at night.
Beyoğlu, Galata & Karaköy
The city's creative heart across the Golden Horn: 19th-century apartment blocks, the Galata Tower, İstiklal Avenue and Karaköy's cafés and galleries. Choose it for nightlife, food and a base that feels like living Istanbul rather than a museum.
Kadıköy & Moda (Asian side)
Istanbul's most liveable corner: a huge food market, third-wave coffee, craft-beer bars and a seaside promenade in Moda. Ferries glide to the old town in 20-25 minutes, and prices for both hotels and meals are noticeably kinder.
Beşiktaş
A lively district on the European shore of the Bosphorus, next door to Dolmabahçe Palace, with young, local energy from its market streets and student crowd. Good ferry and bus links make it a practical mid-range base.
Balat & Fener
The old Greek and Jewish quarters on the Golden Horn: colourful houses, antique shops and slow café mornings. Pick it for atmosphere and photography, and accept slightly longer rides to the main sights.
Top attractions in Istanbul
Hagia Sophia
Built as a Byzantine cathedral in 537 and now serving as a mosque, Hagia Sophia has crowned the old city's skyline for nearly 1,500 years. Its vast dome and golden mosaics remain Istanbul's single most breathtaking interior. Visits are organised around prayer times, so check the hours before you go.
Blue Mosque (Sultanahmet Mosque)
Famous for the blue İznik tiles lining its interior and for its six slender minarets, the early-17th-century Blue Mosque faces Hagia Sophia across a park. It is a working mosque: entry is free, shoulders and knees must be covered, and visits pause during prayers.
Topkapı Palace
Home of the Ottoman sultans for almost 400 years, Topkapı is a sprawling complex of courtyards, treasuries and pavilions overlooking the Bosphorus. The Harem section is worth the extra ticket, and the terrace views alone justify the visit.
Basilica Cistern
A 6th-century underground reservoir held up by 336 marble columns, atmospherically lit and pleasantly cool even in high summer. Look for the two Medusa-head column bases reused from older Roman monuments. It sits steps from Hagia Sophia, so pair the two.
Grand Bazaar
One of the world's oldest and largest covered markets, a 15th-century labyrinth of thousands of shops selling carpets, jewellery, ceramics and lamps. Even if you buy nothing, the vaulted streets are an attraction in themselves — and haggling is expected.
Galata Tower
The medieval Genoese tower on the northern side of the Golden Horn offers a 360-degree panorama over the old city, the Bosphorus and two continents at once. Queues build fast, so come early in the day or book a timed ticket.
Bosphorus ferry cruise
No visit is complete without seeing Istanbul from the water: waterfront yalı mansions, Ottoman fortresses and two intercontinental bridges glide past. Public Şehir Hatları ferries run scheduled Bosphorus cruises for a fraction of private-tour prices.
Dolmabahçe Palace
The opulent 19th-century palace where the Ottoman Empire spent its final decades, built in European style right on the Bosphorus shore and home to one of the world's largest crystal chandeliers. Its waterfront gates and ceremonial halls feel a world away from Topkapı's austere courtyards.

Shopping
Istanbul is one of the world's great shopping cities, stretching from the 15th-century labyrinth of the Grand Bazaar to glossy modern malls on both continents. Prices in lira can be attractive for visitors, and in the bazaars friendly haggling is part of the experience.
Malls
What to buy
Turkish delight (lokum) and baklava, çay and Turkish coffee, İznik-style ceramics, hammam towels (peştemal), spices from the Spice Bazaar, and blue evil-eye (nazar) charms.
Beyond the Grand Bazaar, browse the Spice Bazaar in Eminönü, the calmer Arasta Bazaar behind the Blue Mosque, the antique shops of Çukurcuma, and the food stalls of Kadıköy market on the Asian side.
Best time to visit
April to June and September to early November are Istanbul's sweet spots: mild walking weather, tulips filling the parks in April and a warm sea into early autumn. July and August are hot, humid and crowded, with queues in Sultanahmet at their peak. Winters are mild but grey and rainy with occasional snow — hotel prices drop and the city feels wonderfully local, so it's a fine budget season if you don't mind an umbrella.
Parks & nature
Gülhane Park
The former outer garden of Topkapı Palace, rolling down from the old town to the water. In April it hosts thousands of tulips, and its shaded lanes are the easiest green escape from Sultanahmet's crowds.
Emirgan Grove
A hillside park on the European Bosphorus shore, famous as the centrepiece of Istanbul's April tulip festival. Ottoman-era pavilions, picnic lawns and Bosphorus views make it worth the trip north.
Yıldız Park
A vast, hilly former imperial garden above Beşiktaş, dotted with ponds and Ottoman pavilions. Locals come here to jog, picnic and photograph the Bosphorus glimpses between the trees.
Belgrad Forest
A genuine forest on the city's northern edge with running loops, picnic areas and historic Ottoman aqueducts. It's where Istanbullus go when they need to forget they live in a city of 15 million-plus.
Getting there
Istanbul has two international airports. Istanbul Airport (IST), one of Europe's busiest hubs, lies about 40 km north-west of the centre on the European side: the M11 metro reaches Gayrettepe in roughly 35-40 minutes, Havaist buses run to Taksim and Sultanahmet in 60-90 minutes for around ₺200, and a taxi to the old town costs about €40-50 depending on traffic. Sabiha Gökçen (SAW) sits on the Asian side, also roughly 40 km from Sultanahmet: the M4 metro links it to Kadıköy, and Havabus shuttles serve Taksim and Kadıköy. From either airport allow a generous time buffer — Istanbul traffic is legendary.
Getting around Istanbul
Metro, tram & Marmaray (Istanbulkart)
Load a rechargeable Istanbulkart and the whole network opens up: metro lines, the T1 tram through Sultanahmet, funiculars and the Marmaray rail tunnel that crosses under the Bosphorus in four minutes. Fares rise with inflation, so treat the figures below as approximate and check current rates on arrival.
- Single ride (Istanbulkart)
- ~₺35
- Discounted transfer (within 2 h)
- ~₺25
- Istanbulkart card fee
- ~₺130
- Marmaray cross-Bosphorus ride
- ~₺35
Ferries (vapur)
Commuter ferries between Eminönü, Karaköy, Beşiktaş, Üsküdar and Kadıköy are the most scenic public transport in Europe — a continent-to-continent crossing for roughly the price of a metro ride, paid with the same Istanbulkart. Grab a çay on board and watch the skyline slide by.
Taxi & BiTaksi
Yellow cabs are everywhere but quality varies: always insist on the meter, or better, order through the BiTaksi or Uber apps so the route and price are tracked. At rush hour a taxi can take twice as long as the metro plus ferry combination.
Walking & funiculars
Sultanahmet, Galata and Kadıköy are best explored on foot, but expect hills. Two short funiculars save your legs: the historic Tünel from Karaköy up to İstiklal — running since 1875 — and the F1 line from Kabataş up to Taksim.
Internet & eSIM in Istanbul
Istanbul is covered by Turkey's three national networks — Turkcell, Vodafone Turkey and Türk Telekom — and all three deliver fast 4.5G/LTE across both the European and Asian sides. Coverage is solid in the big malls, on Bosphorus ferries and along the coastal roads; most metro lines and stations have signal too, though you may hit brief dead spots in a few older tunnel sections. Turkcell has the widest footprint nationwide, but in central Istanbul the practical difference between the three is small.
Arriving at Istanbul Airport (IST) — one of the busiest terminals in Europe — you'll find SIM kiosks in the arrivals hall, but tourist packages there are notoriously overpriced, and after a wave of long-haul landings the queue can swallow an hour of your trip. Buying a physical Turkish SIM also means passport registration, and Turkey applies a strict IMEI rule: a foreign phone used with a Turkish SIM beyond roughly 120 days must be registered for a hefty fee, or it gets blocked from local networks. The story is the same at Sabiha Gökçen (SAW).
A travel eSIM sidesteps all of it: install it at home before you fly, and data works the moment your plane touches down at IST or SAW — no kiosk queue, no passport paperwork, no IMEI registration to think about, and no roaming bill. Your regular SIM stays active for calls and WhatsApp verification, while the eSIM carries your maps, translations and ferry timetables as you hop between two continents. Browse current data packs on the Türkiye eSIM plans page before you fly.
Practical tips
- Get an Istanbulkart from a metro kiosk on day one — it works on the metro, trams, buses, funiculars and ferries, and every ride is cheaper than a single-use ticket.
- Cross the Bosphorus on a regular commuter ferry at sunset — it costs about the same as a metro ride and beats most paid cruises.
- Dress for mosque visits: shoulders and knees covered, a headscarf for women; the Blue Mosque lends scarves at the door for free.
- Be at Hagia Sophia or Topkapı right at opening — by mid-morning the Sultanahmet queues stretch for blocks.
- Haggle in the Grand Bazaar with a smile: opening prices often start at double, and accepting a glass of çay is part of the ritual.
- Skip taxis at rush hour — the metro, Marmaray and ferries are immune to Istanbul's famous traffic; if you need a cab, order it via the BiTaksi app.
- Lira prices rise with inflation, so treat any printed fare or menu price as approximate and check current rates on arrival.
- Politely ignore the classic dropped-shoe-brush trick and unsolicited bar invitations around Taksim — both are well-known tourist traps.
FAQ
Which eSIM works best in Istanbul?
A travel eSIM that connects to Turkcell, Vodafone Turkey or Türk Telekom will give you reliable data on both sides of the city. AviaeSIM's Turkey plans run on these local networks, so speeds match what residents get. Install the eSIM before departure and it activates when you land at IST or SAW — no kiosk visit or passport registration needed.
Does the eSIM work on the Istanbul metro?
Yes — most metro lines, the trams and the Marmaray tunnel under the Bosphorus have mobile coverage, so you can check maps and timetables on the move. You may notice short signal drops in a few older tunnel sections, but the connection returns within moments. On ferries and in the big malls, coverage is excellent.
Do I need to register my phone's IMEI to use an eSIM in Turkey?
No — not for a normal tourist trip. Turkey's IMEI registration rule targets foreign phones used with Turkish SIM cards over longer stays (roughly 120 days), after which unregistered devices are blocked from local networks. A travel eSIM isn't a Turkish SIM subscription, so short-term visitors skip the paperwork and the registration fee entirely.
How do I get from Istanbul Airport (IST) to the city centre?
The M11 metro reaches Gayrettepe in about 35-40 minutes, from where you connect to the wider network. Havaist buses run around the clock to Taksim and Sultanahmet and take 60-90 minutes depending on traffic. A taxi costs roughly €40-50 to the old town. Whichever you choose, allow extra time — Istanbul traffic is unpredictable.
Can I pay by card in Istanbul?
Almost everywhere, yes — contactless cards and phone payments are accepted in shops, restaurants, supermarkets and many taxis. Keep some lira in cash for street food, small bazaar purchases, public toilets and tips. Use ATMs attached to major banks and always choose to be charged in lira rather than your home currency.
Is Istanbul safe for tourists?
Istanbul is generally safe, and violent crime against tourists is rare. The realistic risks are pickpocketing in crowded spots like the Grand Bazaar, İstiklal and packed trams, plus classic scams — the dropped shoe brush or a friendly stranger steering you to an overpriced bar. Keep valuables zipped, use licensed taxis or apps, and you'll be fine.
How many days do I need in Istanbul?
Plan at least three to four full days: one for the Sultanahmet classics, one for Galata, Karaköy and İstiklal, one for the Asian side with a Bosphorus ferry, and ideally a spare for palaces, markets or a hammam. Istanbul rewards slow travel — most visitors leave with a list for the next trip.
