We enjoyed our stay at Betsy's very much.
The only downside for us was the heat. It was a hot time of year (July), and in Hawaii, AC is rare...there were fans that helped, but without much wind circulating through the house, it was quite warm, even at night.
But it's a great place in a great location. Betsy is great and communicative when we needed something. The beach is close and it's a great beach with turtles swimming. We were able to snorkel with the turtles which is always a wonderful experience.
We'd stay here again for sure.
