The bad: There is a strong smell coming from the restroom that fills the room, and a different smell that comes from the sink (located next to the bed). There are cochroaches (a common problem in Hawaii), so don't leave any food or dirty dishes out. The fridge and microwave are shared with two other rooms.
The good:
The air-conditioning keeps the space comfortable, which was very important to me. There is a water bottle refill right by the door. The location is great, two blocks from the Hilo Farmers market (which we stopped at almost daily). Plenty of food and shops all around. Despite the smells, the shower and sink were both clean. Check-in and access is very easy. Street parking is available but it becomes 1 hour parking after 8am.
