Great stay at our first airbnb with John and his family in early May 2018. We received an extraordinary welcome as they went out of their way to make sure we had all the info a traveler would want upon arriving (e.g. how to access the house, how to find it, etc.) so there was no need to search through old emails - there were new ones!
We were in a separate part of their home with access to a bathroom down the hall that only we were using (i.e. not shared). There was no A/C but because we're a little above sea level and there was a ceiling fan, a standing fan and a large extractor fan (which we didn't need to use) the room was able to be maintained at a perfect temperature for sleeping even with a blanket on.
Their place is a <10min drive to Kona seafront or a $7-10 Uber if you are interested in some Kona cocktails.
