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 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!
