Great stay !

Location, friendliness, room !
We had a great time at Thalassa. It's situated right in the middle of things but it still manages to keep its class. Food and wine were excellent and the inc breakfast was brilliant, top banana bread. The room was large and very clean. Massive bed with clean white sheets. Enough said about that !! :-) Right next to the Big Blue dive shop who seemed like a nice bunch.....and two of the cutest / weirdest looking dog / cat. One with the most comical, sad face ever seen in a cat. Then the smallest dog with an extraordinarily large amount of white bum fluff. You can't miss it ! Enough waffle, Nice up market(ish) hotel. We had a lovely stay.

Love love love it!

The rooms were extremely comfortable and clean. The hotel is also very central but the rooms are very quiet and peaceful.
Great! Would have stayed longer if we discovered it before our last night.

Perfect location in the village

Location, clean room, location!
Only stayed one night. Right in the centre of the village, great for shopping, cafes, restaurants and the beach. Our room had a strong smell of sewage, but as we were only there for one night, we put up with it.

Nice hotel in good location

Locatio, location and location
Room wasn:t clean and long jair was all over. Breakfast was too poor. Staff didn't do anything more than the regular things to please its customeres. Hotel restotant, according to its menu, quiet expensive so need to look for other options on street.

Awesome, beautiful hotel!

Location, Onsite Tapas Restaurant & Room Style
This place was probably the best we stayed in Thailand. The rooms were very pretty, and they are accurate in their representation on Agoda. Very snazzy boutique feel. The onsite restaurant is a tapas place, very delicious change of pace from all the Thai food. Everyone at the restaurant was super friendly as well. Excellent value for money with all hotel amenities that I would expect in a very nice hotel. Stay here! Super close to the beach and nightlife as well!!

Good value hotel close to the beach

Healthy breakfast. Decor. Close to beach.
I enjoyed my stay but there were some minor irritations. 1) During my 3 night stay my bedsheets were not changed, the cleaner just remade the bed with the same sheets. I reckon if I'd asked they would have changed them but surely all hotels change bedsheets daily as standard? My (cheaper) hotel in Koh Samui did. 2) The cleaners forgot to provide the free bottled water one morning so I had to go down and request it from reception. 3) The hot water was temperamental, it seemed to work perfectly sometimes and be only lukewarm at other times. All in all relatively minor issues but things that I noted during my stay, however I would stay here again.

Great location and cleanliness but...

Cleanliness, location, room
I stayed here 4 nights, we must have lost power 10 times, we were the only place this was happening to on the street. Loud street, so not for those who like to turn in early. Almost never anyone behind the front desk, Restaurant staff is helpful in getting someone, but they act like they can't be bothered, even still, you'll usually be waiting 10 minutes for someone from hotel to help you out. Otherwise great room and location, would stay again.
