The "Turtle House" is a great place to stay for a family. The kitchen is fully stocked with appliances, the beds are comfortable and there is access to wi-fi, cable and even a pool and hot-tub if you want! Our kids also loved roaming the lush property, looking at the koi pond, finding geckos, and trying to name all the fruit and flowers. It was located just north of Kona making it easy to get into town but also to avoid traffic when we wanted to go north or south for other activities.
Karen & Tim are great hosts, had great advice about island activities and volunteered to let us use their beach towels, boogies boards, etc. And above and beyond the role of normal hosts, even letting us borrow a cable to download photos from camera to computer. If we ever go back to the Big Island, we would definitely try to stay with them again.
