Our family of four had a great adventure staying at D'On's place in Ninole. The setting is beautiful and remote, a proper escape. We enjoyed reading on the deck and lounging in the hammock and the kitchen was well equipped. The kids slept up on the mezzanine which was accessed via a very steep ladder - an adventure but worth bearing in mind if you have small children or are less mobile.
The house is about 30 mins from Hilo and there's lots to see on the route between the house and Hilo - waterfalls, hikes etc. We especially enjoyed Rainbow Falls, Akaka Falls and driving the scenic route. Hilo was fun to spend time in too.
