Nothing that other reviewers have already mentioned, but the yurt is a wonderful little rental and the outdoor shower during daytime or nighttime is amazing. My new wife who gets nervous poops even enjoyed the outdoor toilet :) We had practically every meal on the porch with the amazing and peaceful view. We also didn't mind coqui frogs at all; they're loud but we easily zone out background sounds. If you can't handle it, there are ear plugs! The location is also fantastic for anything on the Kona side.
Definitely remember to bring repellant that works for you (the rental does have repellant too), and the guests before who left mosquitos coils were extremely clutch (we left a lighter). Garrett and Sue were very responsive and thoughtful, which made the experience very easy even as they were making improvements to their overall property. I would definitely rent this exclusively whenever I am here in Kona!
