This is a very simple garage remodel connected to a family home. When we visited they had rabbits, chickens and cows. The echo in the unit made it hard to communicate but the remodel was clean and at least had a shower and toilet. The kitchen is just a bar sink with a hot plate.
The view is nice though. I did not find this convenient to any touristic attractions except Waipio Valley and even that was still a bit of a drive. You’d be a lot closer to Honokaa or Waimea. You might as well just drive all the way back to Hilo at that point.
