Beautiful little island, fantastic place to go scuba diving, and of course for lovely beach walks, with an astonishing sunset ;).

The gym is fully equipped with everything needed for a good workout. We will definitely miss the ocean views and infinity pool. Definitely plan on staying here again when we come back to Ko Samui.
