Everything was perfect. The breakfast was amazing with such a big variety of food, fresh produce and great drinks with all different milk options.
Dinner was amazing too - big portions and great selection of drinks and wine. Very friendly staff throughout and always helpful.
The whole hotel was very clean and we felt super secure and welcomed at all times.
The exchange via WhatsApp with the hotel team was amazing and really helpful. Quick response times.
We especially loved the weekly schedule with fun activities such as star gazing or a wine tasting.
After a hectic start in Istanbul, then off to Bodrum, landing at OKU in Kos was pure heaven.
This resort is secluded far enough from town to feel totally at peace, with a great beach club, pool, and divine breakfast.
One of our favorite things to do was the daily yoga and of course, a massage at the spa.
The staff could not have been nicer.
Would absolutely go again.

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.
It was a great stay.Oku is a great luxurious escape from daily rushing life.Thanks to manager Alex and his colleagues we had a great stay.I would recommend highly for the people who is seeking a luxury slow living experience.
The property is absolutely lovely, we especially liked that you feel the nature around the property. The best bit about it, is how lovely the staff are. Katerina in particular was a gem! Would definitely recommend.
Beautiful hotel with great beach and outstanding food. Great daily breakfast spread, delicious cocktails and great atmosphere at dinner. Staff was very helpful arranging a rental car and making dinner reservations. The hotel’s guide book was super useful to exploring the area. Highly recommend!
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.
I had a fantastic stay at Oku. The staff are incredibly hard working and the level of customer service is outstanding. The hotel and grounds are beautiful. The private beach is stunning and lots of amenities. Loved the gym and spa and yoga on the beach. HIGHLY recommend
Amazing hotel, such luxury! Junior suite was fantastic with access to semi private pool right outside the room. Main pool/bar/restaurant area is so chilled and beach a few minutes stroll. Will come here again for more relaxation in the sunshine ☀️
The perfect getaway for a week of recharging our batteries. Beautiful hotel with a perfect private beach directly accessible from the hotel. This was the best place we have ever stayed at. We will definitely be back.
We had the best honeymoon experience at OKU. They upgraded our room to a junior suite, which was absolutely stunning. We also had an incredible breakfast included. The overall ambience of the place was top notch, highly recommend.
