Absolutely loved this rental and everything about it. Rob and Bob were amazingly responsive considering their busy lives and had some delicious baked treats ready for us at check-in (make sure you visit their bakery in nearby Pahoa!). The rental itself is thoughtfully furnished with practically anything you would need. The washer/dryer was clutch for us as we had some sweaty days hiking various places. Definitely look through the provided binder with so much useful local information (restaurant info might be slightly outdated, definitely call before going!) and the guestbooks were fun to flip through.
The location is fantastic for anything on the Hilo side (~45min-1hr) and Volcanoes National Park (~1hr) as well as in the local area, where there are gorgeous black sand beaches, beautiful cliffs, and some hikes. If you enjoy rollercoasters, you'll definitely love the ~3-mile stretch of road leading to the rental :) Definitely take advantage of this gem, I know I will whenever I return to Hilo!
