If you are looking for a respite from all the other tourists on the island, Scott's place is it! It can be a bit tricky to find (especially in the dark), but Scott gives very helpful directions. It is remote and very peaceful, but Hilo is only a 20-25 minute drive away. It's a fantastic location if you plan to spend time in Volcano National Park, as it's only about half an hour away.
Bring a sweater, as it is in any area of the island that is cooler at night. Also, it is loud at night as some other reviewers have mentioned. I loved nature's white noise, but if you are a light sleeper you might want to bring earplugs.
As for the studio itself, it is one of the best value Airbnb's I've stayed it. It's very spacious. The hot tub is fantastic for an evening soak and there are lots of towels available. The lanai is also lovely to sit on in the morning. The bathroom has good water pressure - and more towels. The mattress is very comfortable (on the softer side, but not saggy). The kitchen is a real highlight: the coffee machine is great (but also loud if you want to use it while someone else is still sleeping), there are plenty of pots and pans, lots of cutlery, cooking utensils, cups, and plates, and there was even foil and cling wrap that we used to pack sandwiches for our hikes! It's nice to have the facility to make food when you're so far from groceries/restaurants.
Definitely do not hesitate to stay here!
