This place was conveniently walkable to Kona Waterfront, shops and restaurants. It was exactly as depicted in the pictures, clean and friendly. Reasonably well-stocked kitchen, with additional beer, wine, drinks available for purchase in the fridge. A comfortable place.
Everything was basically fine, but a couple of negatives would be that the smaller second bedroom doesn't have AC, which made it very warm at night with the door closed. The bed in the larger bedroom was extremely soft, not our taste, but maybe others would be okay with it. The overhead light in the living room doesn't really work (the bulbs never lit up beyond an extremely dim state, once we finally got them to turn on at all by fiddling with the pull string... no dimmer switch), so there wasn't very good light for gaming and other interaction in the living room. Shades in the master bedroom don't work. Bedding is a bit tired and worn but fine.
We were also charged an additional "Hawaii tax" of $108 on top of the already inflated Christmas week prices. I think they had mentioned it in the initial post, so it wasn't a total surprise, but it was a separate additional charge after we had already paid the three nights' fee. The other place we stayed Christmas week in Hilo did not charge us this additional tax.
On the upside, Justin was very responsive and helpful. He allowed us to use a washer that had been marked off-limits so that we could wash some towels we used on the beach. He was also very accommodating after a scheduling glitch on our end in the beginning, which allowed us to make a last-minute change and add a day to our stay without a late change fee. Their instructions for accessing the door key, etc were super clear and easy. Very helpful hosts.
Overall, I would recommend this place!
