We spent our first night of a 3-night whirlwind exploration of the Big Island at Michael's AirBnb. We found Michael to be a lovely, easy-to-contact host. The check-in process was simple, but the unit was hard to find in the dark (we were coming from Mauna Kea after dark) and parking instructions conflicted in the AirBnB app.
What made this an 'okay' stay was that the apartment was more run down than the photos suggested and in a location where people were drinking outside in the parking lot nearby (it's in a commercial neighbourhood). We were also woken up at 6:30am by the gym next door.
Overall, it was a 'just-fine' stay. We spent less than 9 hours there and mostly just slept. It was as tidy as it could have been, and with nice coffee as an added touch, but at this price point be prepared for a stay that is more similar to a luxurious hostel than a BnB.
