I stayed a couple of nights in November in the private guest wing of Valerie and Larry's beautiful home. The guest suite was tastefully decorated and had a comfortable bed, desk, portable AC and a private bathroom. A little kitchenette with coffee (beans and grinder!) , microwave and a mini refrigerator was a welcome bonus and added to the comfort of the stay. Parking was easy and beach equipment available to borrow - snorkeling gear, boogie boards and beach chairs.
The house is tucked away in a quite, suburban neighborhood, with the nearest beach a brisk 10 minute walk down the road. Kailua Kona strip with restaurants and shops was a 10 minute drive north - so I would recommend a car for this location. Big Island in any case is not an easy place to tour without a vehicle. That said, Larry did have bikes available to borrow (though I didn't use them). They were friendly hosts while being mindful of my privacy; I enjoyed an entertaining evening chat with them both and their affectionate Schnauzers. I would definitely recommend their place for an affordable, comfortable stay in the Kona region.
