The view of the nature is simply stunning, beautiful sounds of birds surrounding this place and most amazing night sky in your backyard that you can enjoy any time there's clear sky in the night.
What's disappointing was the check in experience, there was no one welcoming us except for the cleaning lady who didn't speak English, which wasn't a problem - the owner didn't communicate to us properly how the check in is done.
Overall, despite very few disappointments, it's probably the best place to stay in Furnas if you're ok with it not being a hotel (they don't have usual housekeeping service).
