Traveller reviews
Hasanen “An outstanding business stay — world-class service, breathtaking sea views, and every detail thought”
25 Aug 2025
I stayed at the JW Marriott Hotel Istanbul Marmara Sea from 20–23 August 2025 while in Istanbul for business, and the experience was absolutely exceptional. From the moment I arrived, the service was warm, professional, and attentive. The staff went out of their way to make me feel welcome and ensure everything was seamless during a busy work schedule. Check-in was efficient, and the concierge provided helpful local advice, including travel times to meetings across the city. The room was spacious, immaculately clean, and beautifully designed, with breathtaking views of the Marmara Sea. The bed was extremely comfortable, and every detail—from the quality of the linens to the quiet, restful atmosphere—made it ideal for both relaxation and productivity. Facilities were outstanding: the gym was well equipped, and the dining options offered a wide variety of high-quality dishes with excellent service. Breakfast was a real highlight, with a generous selection of both local and international options. What stood out most was the level of genuine hospitality. Every interaction—from reception to restaurant staff—was characterised by professionalism, courtesy, and care. It truly felt like a five-star experience in every respect. I would highly recommend this hotel to both business and leisure travellers. It combines luxury, comfort, and efficiency in a perfect location by the sea, while remaining accessible to central Istanbul. I look forward to returning soon.
PAULA “A wonderful and memorable stay — luxurious comfort, amazing staff, and stunning sea views.”

I really enjoyed my stay at the JW Marriott Istanbul Marmara Sea. The room was spacious, beautifully decorated, and spotlessly clean, with a breathtaking view over the sea. The staff were incredibly kind, attentive, and always ready to help with anything I needed. The breakfast buffet offered a wide variety of fresh and delicious options, and the pool and spa facilities made the experience even more relaxing. Overall, the hotel gave me a true feeling of comfort and luxury.
