This place is great. It is pretty secluded, an hour south of Hilo out in the country. The rooftop view of the ocean and stars is absolutely incredible. Even though it's far from town, it's close to a lot of attractions, such as a black sand beach, Kapoho tide pools, and Kalapana (where you go to see the most recent lava flows). Iris and Robert, who manage the unit, are absolutely amazing (Robert stopped to help me fix a flat on the rental car) and will give fantastic advice on things to do in the area.
A couple of things to note that we didn't realize before booking - this unit is the 2nd and 3rd floor of the building, and there is another airbnb on the 1st floor, which is not as separate as we might have liked. Additionally, there is a new airnbnb right next to the house in an old shipping container, and a third airbnb in a separate building just next door. With all of the units so close together, it started to feel just a bit cramped there, and a bit less authentic. Also, all of the water in the house is captured rainwater - this really isn't a huge deal, but certainly makes it less easy to justify the jacuzzi tub.
Overall, we had a great stay and would recommend it for someone looking for a fancier place to stay. It might be worth it for the bed alone - most comfortable mattress ever!
