I really enjoyed my stay. As other reviewers mentioned, Brenda and her partner were extremely generous and welcoming and their property is very serene and surprisingly well-appointed given it’s off-grid. I especially appreciated the communal fridge, good coffee, and endless stack of freshly laundered towels. The bed was also very comfortable.
One thing to keep in mind: the road from the highway to the house is no joke. Any car can technically handle it, but it was a pain to do in my rental car (which I’d promised to only drive on paved roads. Oops). The drive adds 20-30 minutes to anywhere you’re going (Hilo is effectively 50 minutes away, Volcano similar) so be sure you’re ok with that.
