Top Koh Samui Islands Hotel Reviews

Melati Beach Resort & Spa

10/10 Excellent

"This is a spectacular hotel and somewhere to truly unwind. If you have transport or are happy paying around 400bht for a grab taxi each way then the remote location isn't a problem. On site spa and restaurant are very expensive for the quality, which isn't bad, however if you travel to any spa or restaurant the quality of the service and food is always incredible and costs significantly less. We had a pool villa for two weeks and it was unbelievably beautiful, the staff are generally so helpful and polite and the sanctuary pool is by far the nicest pool I've ever been in, so peaceful. I would 100% return here, we rented a scooter and travelled all over the island but enjoyed returning to a peaceful piece of paradise. Thank you Melati"
