Beautiful area, centrally located with respect to Kona, but, importantly, the house is not in the center!
Lovely house-- you can do everything you need to: cook, use the sitting room; nice bedroom. Very quiet.
Great wireless internet --very fast, no problem getting connected.
Great host. Always helpful, with directions, etc. Very pleasant and polite, but leaves you your privacy. A very generous host.

I highly recommend staying at the McGregor's if you want to be in Kona.
