Antigua Villa Santa Monica

There are only six rooms here arranged around a block-wide former private home. Run by César Arias, the founder and soul of the Jardín Botánico, the Posada Corazón has solar power and recycles all its rainwater. The terraces and patios look out on the huge organic garden and fruit orchard that is on the grounds. The eggs for the included breakfast come from the Posada's own chickens. Bonus points: great library.
