1. The place is as clean and new as luxury hotels.
2. The host is responsive and kind. For example, they offered us a well-crafted big shopping bag as a gift. This's so useful that my family brought it with them to Maui, Oahu, and even Asia. Who wouldn't like a big shopping bag with "Aloha" on it?
3. The environment is safe. The neighbors seem to be local people who live there. The place is around 20 minute drive from a major downtown area (Hilo).
4. The host recommended a few restaurants. We tried Hawaiian Style Cafe Hilo (really good) and Nori's Saimin & Snacks (maybe too authentic and too local).
