Me and my wife stayed at the Caryl's ohana for 5 nights and it was a very pleasant experience. The house (a whole first floor) was exactly as pictured and we even realized that it's bigger and more spacious in reality that on the photo. Neighborhood is very quiet and friendly.
Right after we booked it, Caryl sent us a bunch of super useful tips what to visit on the Big Island, where to buy the best and the least expensive food & gas, which was really helpful. The house was fully equipped - from bathroom towels to coffee filters, never run our of anything. There were other guests living on the second floor, although we had almost never met with them and didn't hear them (almost, once we had heard the walking sounds which was a little bit annoying, but it was only one day when we went to sleep early)
