Oku Kos chilled vibes

Very nice relaxed vibes from this hotel group and the staff are always looking to make the stay a little special Would recommend the hotel to my friends because although fully booked the resort didn’t feel overcrowded There’s a private beach to catch the daily sunsets after a nice meal at the restaurant The breakfast spread indeed is nicely varied and the highlight meal of the day Best to hire a car to get access to the other local areas and it’s only a 10 min drive to the airport so you don’t have to feel rushed while topping up the last minute tan

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.
