This is a really wonderful place to stay. You're basically in the rain forest and a quick (10 minute or so) drive to Volcano National Park (so you can beat the crowds pretty easily).
The room was clean and comfortable, and felt really private and isolated. The stay included breakfast (provided the day before with something baked + fresh fruit) to heat up in the room, which was super convenient and tasty.
This is a super romantic place for couples, just because of how unique and isolated it is. But it would work well for families too.
The only minor downsides were really bad internet (don't go here to get work done!), and while the location is beautiful and calming, it's a bit far from lots of stuff in Hawaii. Kona is about 2 hours away and Hilo is about 1 hour away. So if you're trying to use this to venture out, it might require a bit of driving. Because it's so isolated it does get wonderfully dark, which you need to be mindful of if driving at night.
I'd definitely recommend staying here! Hopefully I'll have a chance to come back :)
