We had a wonderful time! J-M's lovely mom Diane accepted our late check-in, greeted us at the house and showed us everything even though it was rather late. The next day Diane gave us tips about where/when to go (and the house is equipped with different kinds of maps and sightseeing information as well). The guest house was cozy and beautifully decorated and it's perfect for a secluded getaway stay, as it's outside of Kona but the drive into the city is only a couple of minutes. Diane was so sweet, she even gave us delicious home-made fudge brownies!
Just as a side note: Diane also provides ear plugs as there are roosters roaming the area at night.
