OKU Kos deserves 10 stars not 5! We could not find a fault! The hotel is gorgeously designed, spacious, quiet and beautiful. The beach is clean and private on a warm sea with pretty views (and free paddle boards and a lovely beach bar/cafe!). The breakfasts were so plentiful and healthy that they saw us through until dinner! Maria (hospitality/concierge), Daniel (reception) and Frosini (spa) were kind, generous, professional and experts at their jobs. We stayed in a two-bedroom villa with private pool and direct beach access - it was heaven. The villa was so clean and the Wi-Fi, a/c, towels, bed linen and shower pressure were top notch. Even though the hotel was full, it did not feel that way. There were always beds at both pool and beach, and the adult-only atmosphere was calm and respectful, but not at all dull. The open air bar at night was such fun - we played cards and boardgames and drank cocktails with our (young adult) children until late in the night! Maria organises evening activities and excursions (open air cinema, beach party, star gazing, wine tasting at a local vineyard) which were great fun - but we also hired a car for the week which meant we could explore the island and have meals out. The hotel is very remote - which is a good thing! - but Kos Town and other island activities are never more than a 20 minute drive away. Perfect. We recommend unreservedly this hotel to both couples and families with older children. The pictures on the hotel website are faithful to the beauty and peace of this establishment. From our delicious welcome drink to a stress free departure we were utterly happy and relaxed at OKU Kos!
