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.

Very nice stay

Probably the best hotel of KOS. It’s a property with 100 rooms (but feels smaller), directly on a white sand beach. The rooms are super comfortable (we had junior suites which share a small private pool). The restaurante is ok’ish. Great breakfast but lunch and dinner options are not amazing. It felt a bit pretentious to us. The service at the restaurant was super nice on breakfast and lunch but, the one time we had dinner (was a very special occasion and I told them that) the service was distant and arrogant. The complete opposite of what you’d expect from the super friendly Greeks.

This is a great hotel in a great location with a perfect beach and pool area. The location is quite remote so you do rely on hotel catering for lunch and dinner. The breakfast buffet is very good with lots of options. The a la carts dinner menu however I found quite limited and given the prices average. One evening in particular I waited so long for food that when it arrived I sent it away hunger over! Had it not been for Maria the concierge manager I would have complained even more but she handled the situation very competently! In conclusion a five star hotel that needs to in my opinion up its game on restaurant food to sit alongside the great location and services on offer.

We had a lovely stay at Oku Kos. Although fully booked it still felt very peaceful which is one of the great benefits of adults only resorts. We spent the majority of our time by the beach rather than the pool as you got a nice breeze from the sea and the loungers were really comfortable. The isn’t tonnes to do in local area (which was fine for us) but the staff are super helpful and assisted with all the bookings of restaurants and taxis in the evening if we wanted to dine elsewhere. The breakfast was amazing, everything you can think was available (which was included in our deal). The lunch menu was also great with lots of options. The menu changed again for dinner with more gourmet options available (mainly small plates), it would have been great to have a few additional options on there, it felt a little limited if you were to eat there every night. Other very small criticism was that we didn’t find the bed/ pillows as comfortable as some similar resorts we stayed at. Other than that all the staff were super friendly and we’d love to come back soon.
