We had a wonderful 5-night stay at the Istanbul Marriott Hotel Marmara Sea. From the moment we arrived, the staff made us feel welcome with their professionalism, friendliness, and attention to detail.
The room was spotless, spacious, and very comfortable. Housekeeping did an excellent job every day, ensuring everything was clean and well-maintained. The beautiful views and comfortable amenities made our stay even more enjoyable.
We are not early birds, then we missed breakfast but i heard a lot of good things about it!
The pool and spa facilities were outstanding. They were clean, relaxing, and provided the perfect place to unwind after exploring Istanbul. The spa staff were courteous and helped create a truly relaxing experience.
What stood out most was the exceptional service throughout the hotel. Every member of the team was helpful, warm, and eager to assist with any request. Their hospitality made our stay memorable.
We highly recommend this hotel to anyone visiting Istanbul and would gladly stay here again. Thank you to the entire team for an amazing experience!
We will back soon! 👋♥️♥️

THIS PROPERTY DEFINITELY BOASTS ONE OF THE BEST LOCATIONS, WITH A VIEW OF THE SEA OF MARMARA. IF YOU GO TO GOLETA, AN UBER RIDE WILL COST YOU NO MORE THAN $20.00 DLS. OR TO THE MALL OF ISTANBUL LESS THAN $15.00 SO IT IS WELL LOCATED. IT HAS ONE OF THE BEST AND MOST COMPLETE AND AMAZING BREAKFAST EVER SEEN AT ANY HOTEL IN THE WORLD.
