Azul Nomeolvides is a small place, only six rooms, quite removed from the world. The rooms are spacious and done rather nicely, if a bit sparse. They're quite open to the world, especially the bathrooms, which are done wonderfully in different stone patterns and feature rainforest-like showers and a wonderful array of lotions such as sunscreen and aloe that you should absolutely try. The owner Bernie is super-friendly, as is the staff and his two dogs very large dogs as well.
A few other points though: A 10-minute achingly slow drive off the main highway 307 to reach the place, over a horribly bumpy dirt road. Not a deal-breaker, but we grew to dread that drive. Not much tables or flat spaces. The rooms' openness means you'll hear the dogs prowl around at night (you'll hear them panting) and much worse, you'll hear all your neighbors. We were the only guests there at first until it filled up Friday night and we heard our neighbors' talk, singing, and music until midnight, even after two other rooms told them to shut it. If there's no noise, the openness is great.
It lists a "restaurant" which, no is a snack bar, a window to order and pick up and only a few tables outside. It's fine, but not a restaurant. We only ate breakfast there and it was excellent. Many creative sitting spaces along the hill descent to view the lake, but note that lots of stairs are involved. We took advantage of their included kayaks one afternoon, a nice touch.
