JW Marriott Hotel Istanbul Marmara Sea

Nice view! Clean hotel! Breakfast was perfect! Polite staff!

The staff was super friendly and professional, and the property was new and classy. The location was convenient, the amenities perfect and the food amazing.

way too noisy and inefficient HVAC, definitely not up to the standard of the hotel

The hotel is wonderful and beautiful, the place is quiet and located on the Sea of ​​Marmara, and the staff are very friendly, helpful . The hotel is very clean.

I tried to find something bad, but I couldn't!

I have been many hotel in istanboul believe this one is best hotel in istanboul with sea view and staff very very friendly Breakfast is excellent and facitily is super

Our stay at the hotel was exceptional from start to finish. The entire property was spotless, and the cleanliness of both the rooms and common areas exceeded our expectations. The indoor pool was one of the highlights of our visit — beautifully maintained, relaxing, and perfect for unwinding after a long day.The staff were incredibly nice, professional, and always willing to help with anything we needed. Their warm and cooperative attitude made us feel truly welcomed throughout our stay. The breakfast was another standout feature, offering a wide variety of fresh, delicious options that we genuinely looked forward to every morning.Overall, we enjoyed our stay to the maximum. The combination of comfort, excellent service, and great facilities made our experience unforgettable. We would definitely love to return and highly recommend this hotel to anyone looking for a wonderful stay.

Nothing to mention, it was perfect

I fell in love with this place the moment I stepped onto the balcony. The sea stretched endlessly, touching the horizon in the most beautiful way. The quiet was almost surreal — it felt like the whole world paused, leaving only the sound of the waves below. It’s the perfect hotel for reflection, rest, and reconnecting with yourself. I would return without hesitation.

Distance from major sights and shopping areas was a challenge. Istanbul traffic made every trip noticeably time-consuming.

We enjoyed the JW Marriott for just one night and had an amazing stay. I celebrated my birthday during my stay and the hotel provided me with a lovely little cake and Macaroons. They also extended club privileges as it was Marriott~Bonvoy days. We throughly and enjoyed the delicious food choices and attentive club staff. We topped off the stay with a couples Turkish Hammam visit, which was a welcome addition to our stay. If you have a layover or are in Köurtkoy part of Istanbul this is a top notch hotel to stay in.

Definitely at least 1/2 hour taxi ride to Galata side of Istanbul.

I recently stayed at the JW Marriott Hotel Marmara Sea in Istanbul, and it was truly an exceptional experience. The room was impressively spacious — much larger than most hotel rooms I’ve stayed at in Istanbul — providing a perfect balance of comfort and luxury. What made my stay even more memorable was the outstanding staff. Every team member I encountered was extremely friendly, welcoming, and genuinely helpful, going above and beyond to ensure my visit was perfect. I highly recommend this hotel to anyone looking for a high-quality and memorable stay in Istanbul.

The location is not so close to the downtown.
