My husband and I have rented Matt's Master Bedroom for two nights. The place is very much as described and the location is in a nice and safe neighborhood. The house is shared with other guests (kitchen and living room), and we did not have a chance to meet Matt. However, he gave us very clear instructions via Airbnb about the check-in and "parking procedure" (sharing driveway with other guests needs some coordination if more than two cars).
Overall, for people who do not mind sharing spaces with other guests and are flexible with their timing on using the kitchen or the TV, this is a good place to stay.
I hope that the issue with the shower in the master bathroom (moldy) Matt will have addressed, but if you are allergic to mold/mildew, check with him before you rent.
