I rented this as a crashpad for a long weekend with plenty of excursions across Hawai'i. It fit the bill perfectly - affordable, clean, quiet and nicely appointed. No frills, but nice touches like a welcome note, fresh water and a small sweet treat. The location is exactly what I was hoping for - close to the Saddle Road for a quick trip to Hilo or the park, 10 minutes from Walmart or Costco, and 15 minutes to Kona.
As I was gone morning to evening most days, I never got to meet my hosts, but communication was prompt and complete, and they were even preemptively apologizing when the neighbors hosted a Christmas party which might have been loud (I was out until later, and didn't hear anything aside from occasional laughter and some music).
The place was cozy, clean and exactly as described; everything worked. The parking spot is convenient and close, if a bit tight/steep.
Highly recommended, and will stay again if I have a similar trip coming up.
