Jim & Rita are fantastic hosts who are extremely helpful and go out of their way to really help make your stay as nice as possible. I highly recommend staying with them, and won't hesitate to personally when I visit again.
The house is one of the most stocked Airbnbs in terms of plates, utensils, knives, shampoo, laundry detergent, iron, etc... I've stayed in. It's located in a neighborhood that's a ~15-20min walk or 5min drive from the center of Kona, with the front porch having a beautiful view of the water.
Yes you do stay in a neighborhood, so they ask you be respectful of the neighbors (and them who live above you) with their noise curfew. It was never a problem for us during our stay.
If you're a really light sleeper it might be worthwhile to bring earplugs just in case. They have beautiful chickens (not roosters) on the property who mostly keep to themselves, but are a bit more active in the morning, however it never bothered me during the week we were there.
