Amazing location and great hosts! Had a great time at Kathy's place - perfect spot to explore the east side of the island. It's close to downtown Hilo, and both Volcano National park and Mauna Kea are a little over 30 minutes away. Would definitely consider again.
One word of caution, sensitive sleepers should bring earplugs - the house is in a residential area with plenty of wild chickens. They can get loud in the morning.
