Sonia's place is a great price and perfectly central in Maui. We loved the Charley Young Beach nearby, and unexpectedly saw turtles there everyday. Several great restaurants and happy hour spots within walking distance and Kalama Beach Park (right across the street) was a great place to watch the sunset.
However I would take an inventory of all of the things in the room upon your arrival, so it is clear to both the host and the guest what items were provided.
