Loved the setting, and the howler monkeys at 4:00 am sound like a lullaby to me. (It's really more of a roar than a howl.) It was quite adequate, if a bit spartan, but hey, it's on the edge of the jungle. Extra marks for the 1.5 km hiking trail that starts over by the yoga studio (unused in the off season) Patricia was a gracious hostess. Her staff make an excellent breakfast (included), the coffee was passable (Costa Rica exports all their best coffee, so a really fine cuppa is actually fairly rare there) and they serve a very large number of choices for dinner (extra) as well, with ample portions. Slight ding because the Wi-Fi didn't work in the cabins, although it was as good as anywhere in Osa in the restaurant/reception area. I would stay here again.
