Reviews from Google“This hotel just stunning. Quiet atmosphere brings you to the mind peace. You do not think about civilization there! Relaxation on maximum! Private beach is just incredible - water amazing and just across the street ! Love it! One of unforgettable vacation i have ever had!”
“This is our 3rd year at Diamond Deluxe and we love it for our annual summer vacation. Quiet, peaceful and relaxing. Amazing breakfast that sets you up for the entire day until dinner. Very friendly staff throughout the hotel. A very large pool which is never crowded, perfect for swimming or relaxing on an air-bed. We will be back again next year in July 2027”
“Exceptional Service We had a wonderful stay at the Diamond Deluxe Hotel in Kos at the end of May 2026. The hotel is situated in a private, quiet setting, but what really sets this resort apart is its fabulous staff. The attention to detail throughout our stay was incredible. The service we received was consistently welcoming and friendly, without exception, from every member of the team. We highly recommend this hotel for anyone looking for a perfect, relaxing and stress-free holiday.”
“Really great luxurious place, service was absolutely superb all week especially waiting staff at dinner/breakfast with a special mention to Chrissa and Zeizan (I hope i spelt that right 😬) and Marcos in the pool bar. Pool was glorious and the food was fantastic. The hotels beach is a bit rocky, but the views and even sunbeds are great! Only minor down side is that theres nothing around for miles. Nearest shops/restaurants are a taxi ride away, about 10-15 euros. Other than that.... lovely holiday.”
“May 2026 break for 5 nights. This hotel does truly live up it's diamond deluxe name. The staff are extremely friendly an approachable. Nothing is too much a request. Clean and bright. Birds and wildlife are free to roam and every morning we were awoken by the birds tweeting away. Rooms are spacious and ours had two balconies, both overlooking the sea and the hills and mountains behind the hotel. The pool is not heated and a bit nippy.....but Im sure is fine when the weather it hotter in July/August Is a little out of Kos town centre but easy to navigate to and there are bike/moped/car rental places everywhere. I would definitely return 😊”
