This is a charming rustic "treehouse" in a secluded area. It feels like you are in the jungle. If you just want a secluded place to unwind it is terrific. There is a little beach that is walking distance from the house that is nice, with lots of shade, but it has a bit of a climb to get down to it. When we were there we couldn't swim because the waves and undertow were too rough. Up the road a ways, 20 minute drive, there is an amazing natural hot spring.
If you want easy access to stores, volcano, sites, etc. this place adds on about a half an hour drive, it is very rural. It stays nice an cool at night, which is really nice. The biggest downside is that it is on a "main" road that can be busy at night for how rural of a setting it is. You definitely need a car if staying here.
Access and availability of the service providing the rental is good. It was very easy to pick up the key and get in.
