Pros : 1) Very helpful staff : check in, help renting the bike, keeping our bags after checkout, providing snorkeling gear. 2) New hotel thus trendy looking. Rooms are new and in good condition 3) Location - short walk to bars, various joints, super market, sairee beach. 4)Good to decent breakfast... More

Starting with the positive - service good and helpful staff - breakfast very good The location of the hotel is in the middle of a busy bar street. So very loud and has quite a cheap feel to it. It is conveniently located to the beach, which is lovely but all restaurants/bars cater for backpackers. We were due to stay... More

Very good quality hotel which is super modern right in the heart is sairee. Had a front facing room but wasn't disturbed by outside sound. Breakfast was good. Can't say I noticed brown water but on check in they did say they had changed filter. Rooms comfortable indeed. Wet room shower area.... personally would prefer a shower curtain but that's... More

Very nice hotel with friendly staff and great location. Rooms are nice and A/C works great. Free cook-to-order breakfast was very good. There are probably cheaper hotels in town, but price seemed very fair. Front desk was very helpful to book tours and taxi's. Only downside was in-room WI-FI was hit & miss, however, I would stay here again.

I fully recommend the Thalassa Hotel who is ideally located at the centre of Sairee Beach, close to all the cool restaurants, bars and the beach of course. The hotel itself is very clean with a very laid back staff and good food. I also like the simple but cool design. I would go back there again if I went... More

The hotel is nice, rooms are small but comfortable. It's in a really loud neighbourhood, so good if you're there for party, bad if you're not. Breakfast is awesome. The staff was friendly but could be a bit more helpful. All in all recommendable.

Stayed for the modern feel and left because of the dirty water. Booked seven nights and left halfway. We got a refund for the rest of our days as we changed hotels. The hotel manager was very kind in refunding the rest of the days as it is usually not possible according to hotel policy. Main reason for the change... More

The Thalassa is in a busy part of Koh Tao leading to Sairee a Beach but don't let that put you off. Firstly the staff are really friendly and helpful. Check-in was quick and easy and our room on the 3rd floor was clean and spacious. The room had a well stocked but not expensive minibar and free water was... More
