Sultanahmet, Karakoy, or Kadikoy: Istanbul's real group-stay decision

Why side-of-the-water is the real decision

Istanbul is split by both the Bosphorus strait, dividing Europe from Asia, and the Golden Horn, dividing the European side into an old city half (Sultanahmet, Fatih) and a newer half (Beyoglu, Karakoy, Besiktas). Ferries, the tram, and traffic all factor into how long a crossing takes, and a group that picks its neighborhood without thinking about which sights and streets are on which side will lose real time every single day to crossings.

As a rule, decide first whether your group wants to be based on the historic peninsula (Sultanahmet), the newer European side (Karakoy, Galata, Beyoglu), or the Asian side (Kadikoy, Moda), and only then pick the specific streets.

Sultanahmet: next to everything, dead at night

Sultanahmet puts your group a short walk from the Blue Mosque, Hagia Sophia, Topkapi Palace, and the Grand Bazaar, which is genuinely convenient for the first day or two of sightseeing. The tradeoff is that the neighborhood is almost entirely built around tourism: restaurants here skew toward tour-group menus and inflated prices, and the streets empty out by 10pm since this is not where Istanbul's nightlife or contemporary food scene lives.

Apartment stock here also tends toward smaller, older Ottoman-era buildings converted for short stays, which is charming for two or four people and cramped for eight.

• Best for: a short stay focused purely on the major historic sites
• Weak point: tourist-priced food, dead after 10pm
• Typical price: EUR 90-140/night for 6-8 people

Karakoy: the strongest all-round base

Karakoy sits directly across the Golden Horn from Sultanahmet, connected by the Galata Bridge (a 10 to 15 minute walk) and by tram, and has transformed over the last decade into Istanbul's design and food district: converted warehouses now hold serious restaurants, specialty coffee shops, and galleries, with Istiklal Street's nightlife a short walk up the hill through Galata.

For a group, this is the base that balances everything: close enough to Sultanahmet's sights to walk or take a short tram ride, in the middle of the city's best contemporary restaurant scene, and walkable to Beyoglu's bars and clubs for the evening. Apartment stock includes more converted commercial buildings with larger floor plates than Sultanahmet, better suited to a group of six or eight.

Kadikoy: where locals actually go, on the Asian side

Kadikoy and neighboring Moda, on the Asian side, are where a large share of Istanbul's young professional population actually lives, eats, and goes out, and it shows in the prices: a group apartment here runs 20 to 30 percent less than Karakoy for comparable space, and the Tuesday market and Moda's seaside promenade have essentially no tourist markup.

The tradeoff is the ferry ride: reaching Sultanahmet or Karakoy from Kadikoy takes a 20 to 25 minute ferry across the Bosphorus (frequent, cheap at around TRY 30-40, and genuinely one of the best parts of a Istanbul trip rather than a chore) plus a walk on either end. For a group willing to treat that ferry ride as part of the experience rather than dead time, Kadikoy is the best value base in the city.

What we would actually book

For most groups spending four to six days in Istanbul, Karakoy is the right default: it minimizes crossings, has the best food and nightlife within walking distance, and has group-sized apartment stock that Sultanahmet mostly lacks. Choose Kadikoy instead if your group is budget-conscious, has more time to spend, and is happy to build the Bosphorus ferry into the daily rhythm rather than seeing it as a commute.

Sultanahmet only makes sense for a short, sight-focused stay of one or two nights tacked onto a trip based elsewhere, not as the base for a full group trip.

Getting between sides in practice

The Istanbulkart transit card covers trams, the metro, and ferries, and is worth buying as a group on arrival (available at kiosks near any major station or ferry terminal) rather than buying single tickets each time. Ferries between the European and Asian sides run frequently, every 15 to 20 minutes on the main Kadikoy-Eminonu and Kadikoy-Karakoy routes during the day, and are both cheap and genuinely scenic, which softens the side-of-the-water tradeoff considerably.
