In general we had a great stay. The loft made for a surprisingly roomy stay, and while the neighborhood itself wasn't terribly walkable, we were 5-10 minutes drive from a large number of attractions in Hilo, so there was no shortage of things to do.
The one issue we had was that the home wasn't cleaned on check-in. That said, Ron replied within an hour, was extremely apologetic, and arranged for someone to come over and clean it right away. It wasn't the best check-in experience I've ever had, but ultimately the rest of the stay was uneventful.
