Great place to stay if you're hiking in the Waipio area. Greg is easy to talk to and is very knowledgeable of the nearby hikes.
As noted in the listing you do hear the sound of kids running around upstairs during the day, but if you're staying here you probably don't plan on being there much during the day anyways. I'm a light sleeper and didn't have any issues getting a good night's sleep to be up early for a hike.
