Cheap laundry service available from the reception
Pretty cheap for Koh Tao (as far as I know).
Location - it's close to everything Koh Tao has to offer, some 10 minute walk to the beach.
We had a little trouble finding it: by the 'Info Guesthouse' label you can find the rooms and then you need to walk another 20-30 meters further to reach the reception which is well hidden and you kind of have to guess if that's what you are looking for.
The mattresses are good for a sleepover but for traveling couples... well, you get the idea.
The room we got had 2 fans instead of A/C. It's not enough, at least for Koh Tao in January.
The worst that happened to us insect-wise was a few ants, which I believe is not bad for an island.
