Nana's house is a great place to live in. I stayed for only a night and I wished I would have stayed longer. We didn't arrived at the house until midnight because we went to Mauna Loa after the sunset to observe the stars. Our tour guide sent us to the house. There were fresh apples in the basket waiting for us when we arrived. The house was so pretty that our tour guide kept saying that she would love to live in this house the next time she come to Kona. The instructions were easy to find. The sofa, chairs and the bed were very cosy. Devices are perfectly ready and you will definitely feel that you are staying in a home instead of a random apartment. But if you are expecting to have your vacation in a super quiet and tidy hotel-like apartment, this house might not be the best choice. The laundry room really needs some cleaning and fresh air... My mom and I kept coughing for a while after entering this room, so then we gave up doing our laundry. But all in all, we are satisfied with this house :)
