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!

Hotel and rooms lovely. Service isn’t the best and very expensive food / drinks wise

Just returned from a wonderfully relaxing week at OKU Kos. It is a truly stunning hotel set on the edge of the dunes leading to a sandy beach and the clear waters of the Aegean. The hotel is designed in a laidback boho style in calming neutral shades. Rooms are cool and comfortable appointed with all you need - a Nespresso coffee maker made me very happy! The bed was incredibly comfortable. Food was fantastic. We were spoilt for choice at breakfast with an amazing selection of granolas, nuts, seeds and dried and fresh fruit. 6 different milks to satisfy any taste and delicious Greek yogurt. As well as a great variety of cooked breakfast and a vast selection of breads. You couldn’t have asked for more. We were half board so enjoyed an excellent dinner each evening. The menu was varied and created with fresh local ingredients. Everything we tried was delicious. There’s a separate vegan menu too. A special mention for the staff who were charming, helpful and did everything to ensure we felt well looked after. It’s advisable to hire a car while staying at OKU Kos as it is fairly isolated, so wandering to a local village is not an option. We took a trip to Kos town and the beautiful mountainside village of Zia. The hotel organised the car hire and provided us with a very useful map with suggestions of places to visit and restaurant recommendations. All in all a relaxing, restorative break in a beautiful hotel which I highly recommend. Thank you everyone at OKU Kos!!
