I would like to thank the JW Marriott Hotel Istanbul Marmara Sea team. The exceptional experience started from when my family and I walked through the doors. 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.
