SER CASASANDRA, Holbox Island, Mexico

The number # 1 selected by the luxury magazine NET-A-PORTER

If your idea of romantic relaxation is to kick off your shoes and pad around in a sarong all day, then Ser Casasandra is your boho beach paradise: think gauze-draped four posters (where staff leave you a Frederico García Lorca poem on your pillow at turn-down), veranda hammocks and sunset mojitos at the bar. With only 18 rooms, one luxury villa and 1.5km of beach to play with, it has an intimate vibe and an easy-breezy ethos; help yourself to bikes and the electric carts or glass kayaks to explore the tiny car-free island and marine biosphere.
