The house is very new and very clean. The size is perfect for a group of 4. Hopefully, after a while it will also become a bit more cozy and usable as some crucial things are still missing (functional cooking knives, dishes (that are not plastic), a dining table, reading lights (all lights are bright ceiling lamps, which is nice, but reading lights would be very nice in the evenings).
A folder with recommendations etc would also be helpful, although I guess everyone has internet access now.
The location is fine if you want to explore the south (Isaac park), east (volcano park), and Hilo. All are 20-40 min away. The only real close point of interest is the trailhead to Shipman beach. And that is awesome!
