We had a great time with our family of 5 in this house. The house is one of the last houses in a very pretty, private street. Next to us was a construction but we didn't hear a sound. The area around is impressive especially the old lava rock fields and the historic fish pods. We had a blast on the two pools nearby and the beaches in the neighborhood. Our friends live in Waimea and highly recommended Mauna Lani.
The house itself is spacious and has everything you need. We think the beds are pretty soft but this is our individual opinion. The panel for the A/C is regulated downstairs for all rooms which makes it a little bit tough when everyone in the family likes another temperature ;-) The prices are very high on and everywhere on the islands but this house + all the Mauna Lani special accesses makes it worth it.
