This new beach resort is sandwiched between the Atlantic Ocean and tropical forest of Barra de Sao Miguel. Stone, thatch, glass and timber are used to bold, modern effect for the exterior, while natural colours and fabrics create a subtler statement in the 11 suites and 12 villas (some of which boast traditional Japanese bathtubs, courtyard gardens or private pools). An elevated outdoor lounge scattered with cushions and low tables is the perfect spot for after-dinner stargazing.
