Already rebooked for next year!!

Enjoyed a 7 night break in September. The hotel is incredible if you want to really relax. This hotel is for you if you want to well and truly switch off. Kos town only 15 mins walk away too if you wanted to get out and about.

I absolutely love this place! For me it’s the perfect hotel - adults only, not too big or small, gorgeous outside, communal spaces and rooms, and great food and drinks. The staff are all so friendly and accommodating as well - nothing feels like too much. We had a late flight and so paid a little extra for a late checkout and we were upgraded to a swim up room for our last day which was the perfect end to our stay. The newly opened spa and gym were also a great addition and we used them a couple times during our stay. Lastly, the local area was also really convenient with a beach, shop and restaurants all within minutes away. We’ll definitely be returning soon!

Great stay! Will come back!

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
