As all the various reviews highlight, this place is a unique oceanfront gem on the outskirts of Pahoa. It's definitely "a studio" (i.e. pretty small/tight, particularly with my 6'3" son as my travelmate!), but extremely well-appointed and maintained. Joe and Cindy pack all the necessary amenities into a nice little kitchen area and a clean and functional bathroom. And the pull-down bed is a neat feature.
The back deck area is also a bit tight, but it's mesmerizing to sit out there and enjoy the beautiful 24/7 pounding of the ocean surf just a 100 yards away. And, yes, it's nice that it's covered (though pylons supporting the house above obstruct some of the view) - so no need to worry about the periodic passing rain clouds. It's a really great place to start or end the day!
Lastly, Joe and Cindy are fantastic hosts - very responsive, friendly and helpful!
