We stayed here for two nights in May and really loved it. The owners were super friendly and made us feel very welcome. Its location is away from everywhere else so you will need your own transport. However this is easily sorted and no matter where you are on the island, you'd want a scooter/car. Rooms are basic but have everything you can need. The sea view was so beautiful, being awoken by an incredible sunrise was magical. It was one of those 'I bloody love Thailand' moments. The rooms are open style, so at night if you leave lights on bugs will come around. But they are only usually active at dusk. There is a mosquito net around the bed to keep the blood suckers out! As its a little open the air circulates and the fan is enough to keep you cool in the night - I slept so well here. The gates lock at 10pm but as Ko Lanta isn't really a night time spot, this didn't matter.
The restaurant upstairs shares the same views as the rooms and had the best pineapple juice in Thailand.
If you're looking at getting away from it all for a few days then this is the place. The next time I come to Ko lanta, I would love to stay here again.
