Location
Santiburi Koh Samui is located on Mae Nam Beach on Koh Samui’s northern coastline. Widely regarded as one of the island’s best beaches, Mae Nam offers soft golden sand, calm waters, and a peaceful atmosphere away from the busier tourist areas. Set across 23 acres of flat tropical gardens, the resort provides direct beachfront access and allows guests to move easily between accommodation, restaurants, wellness facilities, and the beach without navigating steep hillsides.
SAii Koh Samui Villas is situated on Hanuman Bay on the island’s northeastern coast. The bay provides a secluded setting surrounded by tropical vegetation and calm waters, while remaining conveniently close to Chaweng, Choeng Mon, and Koh Samui International Airport. Its smaller footprint and private bay location create a more intimate atmosphere for travellers seeking a quieter coastal retreat.

Santiburi Koh Samui offers an extensive collection of Suites, Villas, Pool Villas, Beachfront Villas, Reserve Pool Villas, and larger Two-Bedroom Villas. The accommodation is notably spacious, with many options featuring generous indoor and outdoor living areas, private gardens, and pools. The larger layouts make the resort particularly appealing to families, groups, and couples seeking additional privacy and room to unwind.
SAii Koh Samui Villas focuses exclusively on villa accommodation, including Deluxe Pool Villas, Pool Villas, and Beachfront Pool Villas. Each villa includes a private pool and outdoor living space, creating a comfortable and private environment. The accommodation concept is well-suited to couples and travellers who prioritise a boutique villa experience over a larger resort setting.
