We enjoyed our stay. While using the Go Oahu card through www.smartdestinations.com. we found that it was the perfect place to stay for exploring the island. The beaches not so much, but there is more to do than the beach. Our hosts were great.
The only suggestion I have is that they get different sheets for the beds. Both beds would come unmade as you sat on the bed. It was crazy and not too comfortable for sleeping. Keep in mind there is no dishwasher. But we really were not there except for breakfast. The laundry was a plus so we did not have to pack. Two blow dryers would be nice, but one was also nice to have so we could leave ours at home. As far as an actual grocery store... it is about 4 miles (15 mins.) away. Not a big deal. There are Costco stores everywhere, but closer to bigger cities (Waikiki and Honolulu).
Overall, this is a great place. We enjoyed our stay. Thanks to our hosts.
