This was one of our favorite Airbnb spots for our entire trip! We were only here two nights, so didn't take much advantage of the kitchen (and restaurants in Hilo are WAAAYYY better than Kona - I recommend looking at Kawehi's recs, especially Moon and Turtle). We did enjoy eating fresh fruit out on her outdoor patio.
This place is awesome - tons of books, antiques on the walls, lots of stuff to notice and take in. It was a very comfortable place to rest between tourist activities, and we have no complaints. I liked how it was slightly out of town - the walk to downtown Hilo was only 10-15 minutes or so. Parking is easy as well, and off-street. We'll recommend this place to friends.
