"Truly a world-class resort! My wife and I stayed here for a week last year and had an incredible time. Some of the friendliest staff we've encountered and our room was amazing. 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. Highly recommended!"
