Our group of two couples stayed there for two nights, exploring Hilo area and Volcanoes National Park. The place is a little bit out of the way, but we had two bedrooms and bathrooms for a good price. Very clean and beautiful house, with some touches that show Lindsay's concern for sustainability, which we liked.
One of these took us by surprise. It turns out, there is a timer on the water heater, so that the hot water for the baths and showers is by default available from 8 am till 8 pm. So, if you plan to take shower earlier or later, like we did, you need to let the owner know in advance. We discovered this feature on our first night. They were kind enough to come the next day and change the settings while we were away sightseeing, so we had the hot shower for our second night there. overall, very pleasant experience.
