What guests think

At JW Marriott Hotel Istanbul Marmara Sea, travelers consistently praise spotless, modern rooms with spacious layouts and sweeping Marmara Sea views, plus well regarded spa, pool, gym, and on site dining, creating a comfortable base for business or leisure.

The seaside setting feels quiet and scenic with nearby malls and a marina, but it is away from the historic center and taxi rides can be lengthy in heavy traffic. Staff frequently go above and beyond, though a few guests experienced slow check in/out or room service that was usually addressed. A small number also noted occasional noise from music or nearby roads. Overall, expect a polished, relaxing base by the sea.

We absolutely loved this hotel. The property has everything that we wanted: great restaurants (one with local food), pool, gym, spa and beautiful spaces in common areas to relax, sit, or read. While not near the older parts of Istanbul, it was not too remote from shops or walkable areas.

Having family nearby, we have had the opportunity to stay at this hotel many times since it opened last year. Front desk sets the tone right from the get go, no matter how early you arrive. They are always willing to help. We appreciated Omer Bey’s help in finding a good room for us, which is not an easy task as we happen to be very particular. We start off our days with an amazing Turkish breakfast, including cooked-to-order gozleme. Everything you eat is as fresh as it gets. Great service by all team members, specifically Filiz Hanim, chefs Yigithan Bey, Harun Bey and Merve Hanim. We appreciate how they take feedback seriously and adjust to our needs. You won’t have to repeat your likes/dislikes everyday; they will get to know you and serve you accordingly with big smiles on their faces. Highly recommend booking an executive room to use the lounge where they serve delicious snacks throughout the day and and hot/cold dishes at night. Gym has top of the line equipment and great trainers, Ozge Hanim, Muhammet Bey and Emre Bey. Ozge Hanim and Ela Hanim at the spa are so sweet and helpful booking sessions. Previous years we tried staying at Sheraton, Hyatt, Polat, Radisson nearby but this JW Marriott blows all of them out of the water. We feel lucky to have such an amazing hotel with great staff near our family and look forward to many wonderful stays here.

A marvellous experience. Best hotel I have ever stayed in and I stayed in a number during my working life. Everything is beautiful and exceeds expectations. The hotel staff are outstanding - without exception. We had booked a panorama room, but were upgraded to an executive suite with amazing views of the Sea of Marmara. It was a very large and well appointed suite. While check-in is at 3.00pm we had access to the suite immediately after we arrived at around 9.30am. You could not have asked for better. The hotel is about 15 to 20 minutes from the main Istanbul areas in what appears an affluent area. There is a marina close by, but you can’t access it by walking along the waterfront as there are residential apartments. But quick access by taxi I would think, although we had meals in the hotel. Finally the rates are good value given the level of facilities and service.

Definitely a nice property. Staff in general are cordial and helpful. The hotel is near a highway and the sound of traffic is annoying. Also main attractions are much farther than what is mentioned on the website. The star rating system in general is questionable in Turkey. Overall Turkish people are very hospitable.

Und der Blick aufs Mamarameer entsprach ganz den hochgesteckten Erwartungen. Die Balkonbrüstungen sind aus Glas, so daß auch vom Bett aus das Meer und der Sonnenaufgang zu sehen sind. Einfach zauberhaft. Schwimmbad und Spa sind ebenfalls sehr großzügig und schön

We were treated with refreshing drinks and the front desk staff (Candan) and concierge were so helpful. The rooms were outstanding, the atmosphere was calming, the restaurants were great. Anything we needed, the staff was helpful with assisting. We especially enjoyed the tasty gifts. The wife was delighted and our mothers have nothing but nice memories. We are already planning for our next stay.

Staff was generally good, some inconsistencies with dining staff from day to day. Really nice view of the Marmara Sea.

Hotel contacted us in advance to ask when we would come. We telephoned and asked whether 2pm would be ok (knowing check in was at 3pm). They said "no problem" and offered to send a car. We declined the car and said we'd take a taxi (we were transferring from another hotel and didn't want the pressure of knowing they would turn up at a specific time). On arrival at 2pm told room wasn't ready and left sitting in lobby waiting ... for 1 1/2 hours. No drinks offered or acknowledgement that we were waiting. Eventually reapproached front desk and complained at 3:30. Complaint was handled very professionally. Hotel did make good by sending written apology and fruit basket plus access to executive lounge, so credit for that. Bottom line is we lost an afternoon when we could have been out and about. If they'd told us upfront not to turn up before 3pm, we would have organised things differently. Other than this no other complaints. Hotel is a bit isolated but very nice if all you want to do is chill after a number of days in Istanbul. Room and balcony were very nice.

The property in general is OK. Nothing too spectacular if you have been around other JW Marriotts around the world. It does not have options for dining or nightlife, very quiet atmosphere. They have a nice location but are not utilizing it properly. Staff is generally friendly if you can communicate with them in English. Breakfast buffet for the price, quality and variety is not worth it. Other 5 star properties in Turkey, offer much better experience. There is no outside pool and the spa area is also pretty dead. Overall, it is satisfactory. They need to really jazz up the place and also make sure they hire staff that speaks English.
