My husband and I stayed at Lapa's Home in January with our two teenage sons, and I can say without doubt that I've never stayed in a house so interesting and creative, nor one that allows such close contact with nature. The living room, dining area, and kitchen are open air, and it was not uncommon for a giant butterfly to flutter through as we were hanging out on the couch. Each day, we watched monkeys swing through the canopy just feet away from us, and we spent a whole morning watching a mama sloth moving like molasses through a tree right beside the living room, her baby clamped like a starfish to her belly. Masses of macaws, toucans, and scores of other birds flew around (and occasionally through!) the house each day.
This open air living is not for everyone, but if you want to experience the wildlife of the Osa, this is the place. The experience is edgy in the very best way--you're not looking at the jungle through double-paned glass in a climate-controlled hotel room, you're living right in it. During cicada season (which is when we were there), that means dealing with the nearby racket of cicadas and occasionally having them dive bomb you at night when they're drawn to the house lights. For me, that kind of experience is a plus--making the tropical experience real and not some kind of Disney fabrication.
We loved the little swimming pool, accessed by its toad-proof stepping stones. We loved the many artistic touches throughout the house created by Michael and Blondie, who were helpful and friendly and gave wonderful tips on where to go and what to do. Our stay there was truly memorable!
