Everything has a funky, fun, Gilligan’s Island feel to it here, and artistic touches and distinct architectural feats make each unit memorable. The namesake Tree House is built on high stilts, reached via a suspension bridge, and features a toilet in the middle of a hollowed-out tree. The three-bedroom Beach Suite features a massive, domed bathroom lit by fanciful portholes and skylights of multicolored glass. Each of the units has a full kitchen, and two are air-conditioned. The whole compound is surrounded by tall rainforest trees, and anyone with a decent eye should be able to spot monkeys, and perhaps even a three-toed sloth. There’s no pool, but right in front of the lodge lies a highly coveted section of white sand beach leading down to Punta Uva. The owners also run an iguana conservation project and follow an impressive list of sustainable practices, ranging from solar heated water and producing their own organic fertilizer to wastewater cleaned by water lilies.
