The realistic view
A 238-room, five-star Marriott in Istanbul's Ataşehir business district on the Asian side, opened in 2007 and renovated in 2018. Guests consistently rate its cleanliness, service and beds highly, along with free parking, an indoor pool, a full spa with hammam and an unusually well-equipped gym — but the Old City is a long ride away, so it suits Asian-side business trips and family weekends better than classic sightseeing.
Good to know
Sightseeing accessCaution

Location
Istanbul, Atasehir
Küçükbakkalköy Mah., Kayışdağı Cad. No:3, 34750 Ataşehir/İstanbul
Rail transit · 423 m
The nearest airport is Sabiha Gökçen (SAW), about 29 km away, which you can also reach by metro from Kozyatağı station. Istanbul Airport (IST) is about 53 km away. There is no free airport shuttle; the hotel arranges paid private transfers on request.
The hotel stands on Kayışdağı Avenue next to the Kozyatağı Carrefour mall, in Ataşehir's business and shopping district. Kozyatağı metro station is roughly 700–840 m away, about a 9–10 minute walk, and the hotel runs a free car to the station if you give guest relations 10 minutes' notice. Palladium Mall is about 1.6 km away and Bağdat Avenue about 5 km. Reaching the Old City means metro plus a ferry from Kadıköy, or a taxi via the Eurasia Tunnel — allow plenty of time in traffic. Bus 129T to Taksim stops right around the corner at Ataşehir Hal.
The stay
A €50 damage deposit is taken on your credit card at check-in and refunded at check-out. Valet parking is €12 a day and EV charging €2 an hour. According to the official site, in-room Wi-Fi is free for Marriott Bonvoy members who book direct. Airport transfers cost extra: €110 one way to Sabiha Gökçen, €150 one way to Istanbul Airport.

Alternatives
Istanbul · Atasehir · ★★★★
A 76-room budget business hotel opened in 2019 in Küçükbakkalköy, five minutes by car from the Ataşehir finance district and a hilly ten-minute walk from Kozyatağı metro. Balcony rooms, a complimentary minibar and pets up to 10 kg set it apart in its class; soundproofing is weak and the tourist centre is far.
Istanbul · Atasehir · ★★★★★
A 165-room business and conference hotel in a 27-storey glass tower in Ataşehir, about 1 km from the Istanbul Finance Center and a few minutes' walk from Watergarden mall. Its 3,000 m² spa, indoor pool and free guest parking are the main draws, but at roughly 10 km from the historic peninsula it suits Asian-side business trips and events better than a first sightseeing visit.
Istanbul · Atasehir · ★★★
An 84-room midscale hotel in Küçükbakkalköy, Ataşehir, positioned for the Asian-side business district: the Istanbul Financial Center, Medicana International hospital and the Brandium-Palladium malls are all close by, with Sabiha Gökçen 27 km away. A small hamam-steam-sauna spa serves corporate guests; there is no pool, and breakfast is often charged separately.
