About
Sumahan - On The Water - Istanbul
Sumahan - On The Water sits in the residential Cengelkoy neighborhood on Istanbul's Asian side, roughly a 10-minute drive from the Grand Camlica Mosque. Housed in a converted historic building, the hotel pairs exposed brick and timber with minimalist interiors, creating a calm, refined atmosphere that feels a world away from the city's busy streets.
Each room and suite looks out over the Bosphorus, with many featuring fireplaces, balconies, and deep bathtubs. The hotel also offers a traditional hammam, a restaurant right on the water's edge, and a complimentary launch service that carries guests across to the European side in about 15–20 minutes.

In brief
What works, what to weigh
+
Strengths
4 reasons to book- Bosphorus views from every room — All room categories, from the Deluxe Room to the Family Suite, face the water, and several feature balconies or fireplaces. The sight of the strait and the bridge is a constant backdrop, praised across guest reviews.
- Private boat transfer included — A complimentary launch service shuttles guests across to the European side in about 15–20 minutes, offering a scenic and traffic-free way to reach the old city.
- Traditional hammam and spa — The on-site hammam and wellness centre delivers an authentic Turkish bath experience, with guests highlighting the quality of treatments.
- Highly regarded on-site restaurant — Dining by the water's edge earns consistent praise, from breakfast to dinner, with a good wine list and standout cured meats.
–
Worth weighing
3 to weigh- Far from nightlife and city centre — The hotel sits in a residential area on the Asian side, so reaching the European nightlife districts requires a long taxi ride. Guests who want evening entertainment may find it inconvenient.
- Small number of rooms — The intimate scale means limited availability, and the property may feel quiet—which suits some, but not those looking for a large resort atmosphere.
- Price and service rated lower than other aspects — The 'Price and service' category scores 7 out of 10, the lowest among the rated categories, suggesting that value for money may be a consideration for some guests.
