Even better than expected. Stayed in Cabin 5, which comes with its own private toilet and shower, with mini fridge and coffee maker. No cell service (TMobile) or access to wifi in the cabin, but that was perfectly fine for us. Spotty wifi on grounds, but we didn't need it. There are very limited dining and coffee options nearby, especially early in the morning, so be prepared.
Coqui frogs called all night - not at all disturbing. Fresh air, so quiet, peaceful and relaxing. We met another guest in the common area and talked all night. Michelle - who stays on the grounds and helps on site - came and chatted a bit. She was very helpful and friendly. She even picked us some oranges for our early departure in the morning!
No microwave, but common area has fridge and cook top. You can make coffee and boil water, if needed.
No issues with pests or wild animals despite the rural area. Saw wild pigs on the road. There is a great coffee farm up the road that opens at 9am - strongly recommended! Lots of free samples and the coffee is excellent.
About an hour drive from Volcanoes National Park.
I literally cannot recommend this place enough, and would absolutely stay here again on my next trip to the Big Island.
