Top Koh Samui Hotel Reviews

Sheraton Samui Resort

10/10 Excellent

"It was an amazing stay, very family friendly. We stayed for 14 nights with our family and we had only positive experiences in the hotel. We loved the beach, pool, food at Blue Monkey and all the staff were wonderful."

Melati Beach Resort & Spa

8/10 Good

"Positives: 1) Location is good, next to high end properties. 2) the layout of the hotel is really nice, with lots of greenery, nice lobby and amenities, and spacious rooms. 3) The staff were very helpful and friendly. Responded well to calls and requests. 4) the breakfast is amazing. Lots of high quality items. They have healthy and gluten free options too. Negatives: 1) Whilst Location is good, it has nothing within walkable distance. Others were closer to the shopping areas. You can hear flights over the resort. 2) We were supposed to get 2 single beds for our boys, but got one sofa bed for 2, which wasn't a comfortable one. 3) the AC in the living room wasn't cooling. We had the technicians visiting twice but didn't really fix the issue. 4) the swimming beach is poorly maintained. We hit rocks and sea plants everywhere. No guests could swim. 5) the gym is average. Not a 5* resort standard."

Silavadee Pool Spa Resort

10/10 Excellent

"The hotel is beautiful. The staff is awesome. The facilities and location are great. I would highly recommend it. The one thing to think about is getting off the property for lunch and dinner. The food available in the restaurants for lunch and for dinner, while tasty, is much higher in price without being better than you can get from any number of restaurants within 30 minutes. It was good, but I would get off campus for more meals if I come back. Everything else was completely top not."
