Joy and Mike's place was essentially as advertised—for four of us it may have been a tad cozy but was a great base to explore Hilo and the Hawaii Volcanoes National Park for two nights.
I have stayed at many AirBNB's and I can say that this was among the most clean places I have ever seen. Combined with the interesting decor and Mike's friendliness we had a great stay and would not hesitate to return.
