My wife and I have stayed at numerous Airbnb's over the past 10 years or so. The Akaka Falls Ulu Tree Plantation is the best we have ever experienced. William, Jane, and Tom are fantastic hosts who are helpful and gracious. We had an extended stay due to construction at our home on the west side of the island.
The ocean views from the front and Moana Kea views from the back ( snow covered top in the winter) are amazing. Akaka Falls is short 2 mile drive and its close enough to volcano for day trip.
My wife and I are already discussing how and when we can get back to visit the plantation in the near future. Definitely a five star destination!!!
