Teresa's ohana is very clean, and a good location for a visit to Hawaii Volcanoes National Park. It's not very far from Hilo, so you can visit the Lyman Museum, too, if you want to. Just like the photo and description, you will be staying in her guest house, with excellent privacy. There's plenty of hot water, with lots of towels. The high speed internet and cable TV worked well, which was nice for staying in touch with friends and family, and for me... watching previous episodes of Star Trek Voyager!
Teresa makes it easy to check in, and is a wonderful source of local information. She recommended that we go to Maku'u Farmer's Market, which is open on Sundays, and this was good tip!
