Mantra Samui Resort
Koh Samui, Thailand
Mantra Samui Resort is an adults-only hotel for guests aged 16 and over, and it is built around the view… It sits high on the hillside above Bophut Bay, so the infinity pool, the restaurant and the sea-view rooms all look out over the water. Guests describe spacious, spotless rooms, a breakfast cooked to order and a team so consistent that returning guests are greeted by the same faces. A spa and a well-equipped gym round out days that can easily be spent without leaving the resort. The hillside setting is also the trade-off. The resort is not on the beach and nothing is within walking distance: Bophut Beach is a 5-minute drive and Fisherman's Village about 10 minutes, so most guests rely on taxis, the shuttle or a scooter. Couples who want calm, space and a pool with a view will be well looked after; anyone who wants to stroll to the sand or out to dinner should look closer to the beach.
Why this position
Rests on more guest reviews than #12 (993 to 510), at a slightly lower score (9.0 to 9.1).

Moorea Boutique Resort Samui
Koh Samui, Thailand
Affordable luxuryMoorea Boutique Resort Samui is an adults-only hotel for guests aged 16 and over, and its size is the point… With 17 rooms and villas set around gardens and a saltwater pool in Ban Tai, it feels more like a cared-for private house than a resort. Guests talk first about the staff and the owner, who is often on hand, then about the detail: immaculate grounds, sculptures and plants, lights in the trees at night and spotless rooms. The kitchen gets warm praise too, and Ban Tai Beach is a 2-minute walk away. The calm comes with trade-offs. Ban Tai is a quiet stretch of the coast, so shops and nightlife are a ride away, and some of the bungalows and villas are compact. A few guests also felt the price called for a bigger gym and a more varied breakfast. Couples who want peace, design and personal attention will feel at home; travellers who want buzz on the doorstep should look elsewhere.
Why this position
Among the three highest guest scores of the 15 hotels we rank here: 9.5 from 405 reviews. Scores higher than #13 (9.5 to 9.0), on a smaller body of reviews (405 to 993).

Buri Rasa Village Samui
Koh Samui, Thailand
Buri Rasa Village Samui is an adults-only hotel for guests aged 16 and over, and it combines a beachfront address in central Chaweng with a surprisingly calm, village-like setting… Rooms are spread through lush gardens a few steps from the sand, and guests describe them as spacious, clean and well designed. The pool sits close to the beach, sunbeds are kept for guests on the sand, and the spa's massages are a frequent highlight. Above all, guests talk about the staff, who are praised from The Beach Club to housekeeping, and some come back for repeat stays. The trade-offs are small but worth knowing. Breakfast divides opinion, with some guests wanting more variety, and the green garden brings its share of insects. The gym is basic, and a few guests had wifi drops or a noisy air conditioner. Couples who want the beach and Chaweng's restaurants on the doorstep will be well served; anyone after a secluded stretch of coast should look elsewhere on the island.
Why this position
Rests on more guest reviews than #14 (791 to 405), at a slightly lower score (9.3 to 9.5).
