We had a FANTASTIC stay 3-10 June 2026 and was very impressed by the quality of rooms, helpful staff and more importantly the overall experience and chilled energy the hotel gave us - it was exactly what we needed and will visit again hopefully next year. If you are looking to switch off and are ok to stay at a hotel a little off the beaten track, then this is your place. 100% recommend.

We recently stayed at OKU Kos and were absolutely blown away. Everything about this hotel is carefully designed and curated for the ultimate relaxing getaway. We stayed in a pool suite, which was wonderful —incredibly private, quiet, and the perfect space to unwind. The staff truly went above and beyond, with little chocolate treats delivered daily. They couldn't do enough for us, and were consistently kind, fun, chatty, and helpful. The amenities and activities were an added treat. We loved participating in the morning yoga classes, enjoying the beach party, and even taking a cookery class. The beach itself is gorgeous and goes on for miles, worth walking along and dipping in to cool off. As for the food—it was truly top-notch and Michelin-standard. The breakfast spread offered an amazing amount of choice, and our three-course half-board dinner was heavenly taste-wise every single night. We couldn't fault the place in the slightest. We would more than recommend to anyone looking for a stylish and luxurious adult only Greek escape!

We stayed for 7 nights at the Oku Hotel in Kos for our honeymoon, and it was absolutely perfect. Our room with a private pool felt like our own little paradise – stylish, peaceful, and private. The atmosphere of the hotel is calm and beautifully designed, with a focus on relaxation. Every detail, from the comfortable bed to the amazing food, made our stay feel special. The staff were always kind and helpful. We couldn’t have chosen a better place to celebrate our honeymoon – we left with the best memories and can’t wait to return.
