"Stunning property, let down by management and privacy issues. OKU Kos is beautiful. The 20m pool is spotless and great for fitness. However, our room's private pool lacked privacy; gaps in the walls allow neighbours to see right in, ruining any chance of skinny-dipping. The beach is stunning with comfy sunbeds, though it gets very windy.Food is a mixed bag. Breakfast is outstanding with perfect poached eggs, and the bar staff serve wonderful cocktails. However, the chef consistently overcooks fish. We had to send a tuna dish back, though they did compensate us with free drinks. Spa treatments are good, but note the hammam and sauna cost extra to turn on.Guest services need major improvement. First, the hotel tried to downgrade our room category pre-arrival, forcing a stressful 3-hour phone call with our travel agent to fix.Second, the Guest Services Manager ignored our pre-arrival emails and only said a brief hello on night three, seeming clueless about our profile.Third, swapping half-board dinner for lunch was a struggle, though a kind receptionist eventually helped us on our final day.Finally, for the World Cup semi-final, they just gave local suggestions instead of offering to make a booking for us. This is not luxury concierge service.It is still a great location for couples or groups, but do not expect true 5-star service."
