The hotel agenda is “the art of slow living” and they fully stand behind that. A peaceful gem which is super modern and well designed. The service and food are outstanding! The dinner is something you should not miss.

A lovely relaxing hotel, primarily set up for couples. Setting and ambiance are spot on, always feels quiet and like you have your own space. The styling of the hotel is quite unique and very contemporary, it helps to create the right atmosphere. I would definitely stay again, we had a shared pool, which worked well, glad I didn’t go for the private pool, as all the pools a quiet enough. Rooms are very well attended and cleaned. The hotel serves one of the best breakfasts I have ever had, great setting, service and choice. Only negatives, the gym is very small and one of the treadmills was broken all week. The same goes for the Hammam, which was being fixed all week. Also, at times the staffing can be minimal and drinks take a while, but generally the staffing is very good.

Pros: Nice property- peaceful ambiance and well maintained Nice pool- good temp, loungers spacious and available Food is good Breakfast is good (not the buffet, but the a la carte menu) Cons: -Found COCKROACHES in our bathroom two out of four nights of our stay. Complained after the first sighting but nothing was done. Staff was not apologetic or helpful in any way. - hotel is not located directly on the water (town is a 30 min walk). There is no view. The outside surroundings are dirty and not well kept. The “beach club” is a short walk but there is no service, food, etc. - very rudimentary and not reflective of the rest of the hotel; needs improvement - Staff and concierge seem to be inexperienced, with questionable advice regarding things to do and other companies to use. On THREE occasions, they did not book reservations they had confirmed they booked, so when we showed up to the restaurants/ beach club we had to be squeezed in and accommodated last minute

Staff were super friendly and very accomodating. Room was nice with a comfortable bed. Food is lovely too. The only negatice thing is the noise from the beach bar down the road. Music goes on until roughly 12 a.m. There was also construction noise going on next door and gardening noise in front of the spa.

Amazing hotel!

Best hotel in Kos! Everything was amazing, and the service stood out. The staff was beyond friendly and took the time to help find us local dinner reservations, walk us through things to do on the island, and answer our many questions. Maria was so kind! I did not get the name of the other girl at reception, but she was also so helpful! The atmosphere and amenities were top tier. We decided to upgrade to the room with the private hot tub which was very much worth it. The breakfast was also top notch. Worth every penny and would stay here again if we return to Kos.

Very nice luxury hotel, on the outskirts of the main town of the island. Very good breakfast and amazing rooms. The service should be improved tough, especially for what concern the beach and umbrella availability on high season.

Great stay

We had an amazing week's stay at Theros. The hotel is very nice, with great options for breakfast, lunch and especially dinner. Everything was very clean and worked well. The hotel organised airport transports for us, as well as transports for a dinner further away from Kos, which was great. They also helped us to rent a car for a day. The hotel is a 15-20 minute walk from Kos Town which might seem like a negative, however the beach walk there is very nice and is filled with beach clubs, bar, restaurants and the like. Overall, we had a great trip and would gladly return.
