We enjoyed our stay at Barry's place. It was attractive, nicely appointed, clean, well stocked, had washer and dryer (and supplies), a 65" tv on the wall, a new grill, snorkeling gear and boogie boards, etc. - in other words it had everything that we needed. It was ideally situated for us (i.e. in a quiet neighborhood away from the noise and crowds of Kona, but plenty close enough to make a trip to Safeway, Walmart, or downtown Kona very convenient). By the way, the views (particularly the sunsets) from this home are spectacular.
One thing that we wondered about before our trip was whether having no air-conditioning would be a problem for us (particularly for sleeping at night). It was not a problem. With ceiling fans in every room and plenty of big, airy windows to allow air to freely circulate through the house; we were comfortable during our entire stay.
I called our host, Barry, a couple of times with questions. He was always accessible and very helpful.
