We spent 2 nights at Mai's place just after Christmas, and definitely enjoyed our stay! It is certainly cooler in this part of the island, and we appreciated it after the heat of Kona. The two nights we were there, it rained heavily both nights, which didn't bother us in the least--it was lovely hearing the rain on the roof :). During the day it did not rain at all, and it was a lovely cool temperature in the house. Our long-sleeved shirts/light hoodies were pulled out and kept us comfortable.
The house was very clean, and we appreciated the Christmas decor. The kitchen is well stocked with plates, cutlery, cooking gear, etc, though based on previous reviews, we made sure we brought our own stapes such as salt and assorted spices, sugar, etc in addition to our other groceries.
The beds were comfortable and there were sufficient linens for the pull-out couch. You could hear some noise from the highway and occasionally from the adjoining unit, but nothing that kept us from sleeping well.
Mai kept us well informed with how to check in and making sure we were satisfied. We would recommend this as a unique change of pace and environment from Kona.
