My fiancee and I recently stayed at this house, and our only complaint was that we wish we had stayed longer! The house was great, very clean, and has all of the appliances you would think you'd ever need for a vacation. We cooked our own meals while here, and had the privilege of grilling out on the deck with a beautiful ocean view. The kitchen is well stocked with various things for cooking. The bed we stayed in was also one of the most comfortable beds I think I've ever slept on. The garden out back was beautiful and was a great place to eat breakfast in the morning.
Our favorite thing was all of the beach equipment on hand for use. We took advantage of the snorkeling equipment and saw some beautiful fish and coral at a nearby snorkeling area. There are also tons of beach chairs, towels, picnic bags, and other miscellaneous beach fare.
While we only had 2 people staying here, you could easily accommodate bigger parties, probably up to 6 or so people I would think. It is very spacious.
Overall, a great experience, and when we (inevitably) come back to the big island, we will probably be staying here again. Definitely recommended!
