My wife and I stayed here for 3 nights in April and enjoyed our stay! The place was clean and the hosts were very nice. They gave us a wonderful dinner recommendation and even gave us a bottle of wine to celebrate our honeymoon! The highlight of the accommodations was the two cruiser bikes available. They made it easy to bike down to the beach, grab some breakfast at "Little Fish" down the road, or explore the area.
Something that we would have liked to have had with our accommodations was a few more smaller amenities. Things like a full spice rack, more cooking dishes, a full size shampoo/conditioner, sunscreen, etc... These were common items at some of our other stays in Hawaii and were anticipated when staying at a detached property with a full kitchen.
Another thing to note is the privacy component of the stay. Personally, we did not have any issues with privacy, However, the cottage is a stand alone building that is surrounded by housing on all sides and you share the outdoor property with the host family. In my opinion, I think the listing does not accurately depict the level of development around the cottage. With that said, everyones definition/expectation of privacy is a bit different.
Overall, we would recommend staying at the cottage!
