We had a lovely almost week-long stay at the Oasis. It was very convenient to have a 2nd bathroom, large washer and dryer, laundry baskets, and the beach chairs and towels. Everything was new and clean. It was nice and quiet at the end of the street (except for the frogs that provided perfect white noise during the night). I also enjoyed talking to my two new gecko friends while lying in the hammock on the front porch.
There was good communication and we had everything we needed. We would stay here again!
Note: there is no a/c, like many places in Hawaii, but the fans/windows open make for good sleeping in the evenings. It does get a little warm during the heat of the day, if you're used to a/c.
