It is definitely a secluded place! We didn't have the courage to go down to the river/waterfall to swim but it did look lovely from the window :)
Everything was as described, though the towels and face cloths were a bit musty. It is indeed a tiny home and there is not a ton of space to put your bags, but we made it work!
The location is awesome for sightseeing. Close to akaka falls and the Botanical Gardens (HIGHLY recommend), and pretty close to volcanoes National park too!
