Jason's place is pretty much as described. We found it very easy to let ourselves in. The room was clean and we had enough space for our bags. We found free parking right in front of the house every evening during our stay. We never saw Jason but he left some printed info about the house and the city.
The only downsides I can think of are that the bathroom is potentially shared with another AirBnB guest, and the room can only be locked from the inside. I guess it boils down to luck. We didn't have any problems with the other guests, although one of them did leave a lot of their personal stuff in the bathroom.
