Exceptional 10.0
Superb stay !
Not much to say other than a very comfortable stay with a great team. It made it all the more appealing as it is adults only and therefore no screaming kids to put up with. 😁 A very professional, friendly team, great food and always something to keep you occupied. Thank you and see you again.

Place to relax. No kids running around.
I didn’t think “adults only” meant this much when my wife and I wanted to get away from busy daily life and de-stress. Pool and beach side sunbeds are perfect to spend hours to lay down, nap, read or just look at the blue sky. Drinks are not that special but definitely good enough to sip under the heat. Breakfast is not with huge selections of food, but again just enough to enjoy for 5 days for me. Fresh fruits, egg dishes made a la minute, some Asian dishes, variety of bakeries. Staffs are very friendly including some of the western management guys. Always with Thai smiles. We booked ocean view room, and the view from the room 442 was magnificent. Hotel gym is well-equipped and available for 24hours. There’s a convenience store, 5 minutes walking, and also laundry place which was THB 40 per kg (pick up in 24 hours). Hotel offers shuttle bus at reasonable price to famous Fisherman’s village (restaurants and beach bars) and Chaweng beach (shopping mall, Central Festival). My wife and I loved the place and we will comeback for our next Samui visit.

Would recommend
This hotel was great! We stayed here for a week during our honeymoon. The rooms were clean and serviced well. Our view was amazing. The breakfast was great. We loved the pool and the pool bar. All of the employees were so kind. All services offered were great, especially the shuttle services and motor bike rentals. The only thing I will mention is that we were excited to use the pool table one night, but found out it didn't work after having been advertised to us at check-in. Overall, I would recommend this hotel and stay there again.

That pool though!

Cannot fault staff, service and cleanliness
The staff, service and cleanliness was absolutely perfect - the only reason our overall rating isn’t the highest it can be is due to personal preferences regarding the location and facilities.
