"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!"

"Loved the restaurant and the staff working it. Food was amazing and staff were so accommodating and kind. Shower had low pressure and did not hold consistent water pressure / temperature. We stayed for two nights and requested a replenishment of supplies. No towels were exchanged and we were left no sanitary bags- which I feel there should be plenty considering the resort requests that you do not flush anything down the toilet. Overall it was a nice stay. "
