We arrived in Koh Tao having not booked anywhere and were horrified by some of the prices being asked for some rooms (we are on a budget!!), so we reached Sunset Buri and found these rooms going for 500 Baht, located on the ground floor near reception and took them.
The room was big and spacious, with a fridge, fan and hot shower (which was one of the best I have used in our trip round South East Asia). The room did smell a little of stale cigarette smoke and looked a little dated, but other than that it was clean and comfortable.
The Staff were very accommodating, and had no issues with us moving to a different room (we only moved to access the wifi from a local cafe ;-) ) and also agreed to a discounted rate of 450 a night as we were staying 6 nights.
With regard to some of the comments relating to theft on here, we always took our key with us whenever we went out, and never had any issues. The room was accessed by hotel staff for cleaning when we were out. We did see that the keys were left at reception and easily accessed by others, so can only think that the thefts reported below were done by other opportunistic travelers.
The resort itself was ok, nice pool area, spoilt by the pool itself! We did use it, but the water was mirky with dead insects floating on top - it didn't seem to be cleaned often. Sun loungers etc all appeared to work and be in good order.
Think it was referenced in another review, but the resort does seem to be bombarded by locals in the afternoon who use the pool. Wasn't a problem to us, and there was still plenty of room.
All in all, decent room in a good location on an ok resort. Good value for money when compared to some prices we were quoted, sure you can get bungalows for 350/400 baht at other resorts, but these were full!
On a side note, I can't find the restaurant on TA, but we ate at a restaurant called Su Chili (4 out of 6 nights!), located near by, and would highly recommend it - dive masters from several companies were in here on every occasion we went - well worth a visit.
