Our stay at Carme's place was wonderful.
Parking was fairly simple. We never found any spots on the street but there is a large parking lot at the end of the next block that was easy to get it. NOTE: there are some rows that are reserved on Wednesdays for a market. If you park there on Tuesday night and don't move your car before 6am you WILL get towed...I speak from experience.
The proximity to public transit was amazing. Either right across the street, or on the next block.
The apartment is lovely and well equipped. There wasn't anything we needed that wasn't provided.
Carme was a fantastic host and was quick to respond with anything we needed. We had a wonderful time in Bologna and if we ever make it back we would definitely stay here again!
