This super-sleek hotel takes over a small private island just a little offshore of Koh Samui. The 22 pool villas are bordered by a long stretch of white sand, which connects with Samui at low tide. Interiors combine wooden construction, wall panels, high ceilings and earthy tones with splashes of blue. Go for the hilltop Ocean View Pool villa, which opens out to a picture-perfect private plunge pool overlooking the sea.
