This is a great place in close proximity to Volcano National Park; great for any adventures on the Hilo side of the Island. Yes it is off grid but all modern amenities were available and seemed in good supply despite a few low sun days which limited the solar panels.
There is a back up generator just in case but we didn't need it. The road is full of potholes but if you take it slow you it should be no problem. Our kia rental sedan made it through so anything should.
Host is super responsive and pleasant.
