Purple cottage was comfortable and mostly peaceful., and the bed was more comfortable than home. We loved the sounds of the frogs and the stars in the clear skies, especially from the hot tubs. (There are 2!) Don't expect to be doing too much cooking...the sink is in the bathroom, which is serviceable if awkward. Large dorm fridge.
Location is good, especially since the Red Road no longer goes through, and if you stayed down there you'd need to be doubling back a lot. We certainly enjoyed Kehena beach down there, though. We thought the Thai restaurant in Pahoa was Fantastic, especially the complex and flavorful curries with lot of veggies. (We like it spicy, but it you don't, let them know. Our "3 stars" was equivalent to 4 or 5 stars in Seattle.) Only an hour drive to Volcano NP, but note that if you want to see the glow of the lava, it's best to go at night. The parking lot by the rim trail to the viewing area fills up, but at 8pm was opening up.
