If you like/want to live in rural part of eastern side of Big Island and not too far away from Kona, this is a gem. It's less than 10 minutes away from awesome 2 step snorkeling and National Historic Site. At night, accompanies by sound of nature and waken up with sound of rooster and seeing ocean at the tip of our toes was beautiful.
Host did a fantastic job with the space, toiletry, kitchen wares, even had grounded Peet's coffee. Thoughtful touches like ice cooler bag for packing cold drinks and snorkel gears guests can borrow. Although you live in the middle of Kona coffee farms, I would suggest go out and discover some of your own favorite farms. Although a smaller space, but it's more than adequate for two people, and especially having experienced Tokyo apartment myself, it's plenty of space.
On the same street, there is painted church in walkable distance, also a buddhist botanical garden and whole bunch of coffee farms in very close by area.
