My boyfriend and I went to Lonely beach in November 2012 and we stayed at Siam Hut for 5 nights. We loved it. Bungalow was very basic a big double bed, a fan, and a bathroom with cold shower (we can get air con + hot shower + front row for a little bit extra) but clean. We brought a hammock which we hung on the terrasse of the bungalow and that was lovely to be able to read a book while having a sea view. The beach is lovely.
The restaurant was nice, we had lovely food there (try the spicy squid salad) and very nice location. The staff was lovely, especially the older lady that brought the food to the table always wanted to make sure that everything was fine. They also have cinema nights and parties. The only complain I have to make about this place is the lady at the bar where you order you food/coffee in the morning. She was totally unfriendly and quite rude at times to the people staying here.
Well, if I go back to Koh Chang I will defenitely stay there again.
