We stayed at Kevin's place for a week with our dogs. The house is at a great location, few minutes walk to the downtown and down the street from o.k. farms next to the waterfalls. The house is tastefully decorated and comfortably furnished.
We were visiting during the thunderstorms and had some very hot/humid days, the whole house fan did a really good job of cooling the rooms quickly.
We ordered food from Hilo restaurants for all of our meals, so didn't use the kitchen much, but it looked well equipped.
Overall we had a pleasant stay and highly recommend it for everyone looking to stay in Hilo.
