This house was just as advertised. We are a family of 6 - two parents and four young adults. This was home base for a week while we explored the island. The house is tastefully decorated with a decent kitchen, plenty of bathrooms/showers, and comfortable beds. I especially loved the large balconies both downstairs and upstairs, well appointed with furniture. We all used these during downtime.
The upstairs can be used as a separate apartment and has a small kitchen area and dining table (which we used for D&D in the evenings). The beach is literally a minute's walk away. One morning a seal was sunning itself on the beach 20 ft away from us. I wouldn't recommend this beach for swimming. Our favorite swimming beach was Salt Pond Beach a short drive from the house, which had great snorkeling.
The town of Waimea is about 1.5 miles away - we walked to it once (and it's a nice little town), but most places we went were 20 minutes to an hour away.
Overall, 5/5 - great location, great house, will probably rent again in the future.
