We stayed for one night and it was everything we expected. Although we had to wait to check-in a little later than we wanted, host was responsive and let us know as soon as it was ready.
The house feels very private even though you are surrounded by glass, and the location is amazing for visiting the national park. We were so excited to get a night booked during our trip as this is obviously usually booked. Will definitely try to visit again next time we are on the big island!
