If you're not a light sleeper, not sensitive to varying temps, and don't mind staying extremely far off the beaten path, this may be a good place for you. Our stay was very short. We ended up only sleeping there for a few hours between a late return from Mauna kea and an early sunrise trip to the volcano.
Pros:
-cheap
Cons:
-birds chirping half the night was less than relaxing. A dog also woke me up barking a couple times. The windows are not very sound isolating
-no heat or ac that we could find. This wasn't a problem for us but I imagine it could be during summer and I didn't see mention in the description
-bed was not very comfortable
