Great experience! Everything was as it was listed.... actually, it's better. This is a perfect hub for exploring or just simply staying outside the crazy tourist traffic. There's plenty of parking in Kona, there's no need to stay in a tiny hotel room. Kelly and Francesca's place feels homey immediately.
Even though it's close and convenient to the airport, you cannot hear planes. Planes land and depart north and south, this place is just east. Pleasently surprised.
Everything was super clean. We met the hosts, they are a 100% normal couple. Better than normal, actually.
I'm super particular and can't think of one thing to complain about. Really really happy!
