About
Jw Marriott Hotel Istanbul Marmara Sea
JW Marriott Hotel Istanbul Marmara Sea brings a contemporary, design-led stay to Istanbul's Ataköy district, along the Marmara Sea shoreline. Rooms are set up for long stays as much as short breaks: most include a sitting area, tea and coffee facilities, and some residences add a washing machine and kitchen utensils. The hotel's position by the water means many rooms take in the sea, and the terrace and garden furniture give you places to enjoy it.
When you're not in the room, there's an indoor pool plus a seasonal outdoor infinity pool, a full spa with sauna, Turkish bath and massage, and a fitness centre with yoga classes. Dining runs from a buffet breakfast to a poolside snack bar, with the on-site Akira Back restaurant a particular highlight for guests. For families, there are cots and a children's buffet; for business, a dedicated centre and meeting rooms.

Worth weighing
4 to weigh- Location scores lower than other categories — While the sea views are a hit, the location category sits at 7—lower than rooms, dining, and service. Some guests may find the Ataköy area less central for sightseeing.
- Rooms and cleanliness could be improved — At 8/10, rooms and cleanliness are solid but not top-tier for a five-star property, which may matter if you're particular about room finishes.
- Price and service value is mid-range — The price and service category is rated 8, suggesting good but not outstanding value for the level of service on offer.
- No pets allowed — The hotel's no-pets policy means you'll need to make alternative arrangements if travelling with an animal.
