I was there 2 years ago. Stayed at Ao Kiu Na Nok and also at Ao Korang, which are the last two beaches (most southern tip) on the eastern side of the island Samet. I wanted a very down to earth (down to the beach) bungalow and got some very secluded ones. Was fantastic. Very basic but very private. Some are built on the sand and some on the rocks overlooking the sea. There is also a tree house hanging right over the water! Costs are Bt100 (treehouse) to Bt400 for the larger and better bungalows. Take your own boy and have a great time! Some nice restaurants nearvy. Hardly any seafood. Avoid Thai holidays, and even weekends as it gets a lot of local traffic. Not too many farang.
