The place is unique for sure. There are no glass windows, only screens on the windows and doors. This shouldn't be an issue if you are ok being outdoors. My wife and I however were not, so it felt like we were camping to some degree. The shower overlooks the shared driveway but there are some curtains. The place is pretty cool otherwise.
Please note, due to the current volcanic activity there is volcanic smog in the area. It varies from acceptable (most of the time) to unhealthy (rarely). We were pregnant during our stay so there was some worry. We ended up staying at a hotel the first night due to a code red unhealthy forecast.
We hope the VOG gets better since this place provides a unique experience.
