It's hard to stay in a better location to explore Bologna. There are public parking garages (small ones, but no issues to park on a Thursday late afternoon) close by if needed, and then you can walk the city after checking in. The check-in process was not as smooth as it could have been. Response time of the host was a bit too long, and we waited 10 minutes after our estimated time (we arrived 5-10 minutes before that, but that's on us) in the heat of Bologna before being able to get to the apartment.
Despite having received confirmation that the sofa bed would be made, apparently the host did not communicate this to the friendly woman in charge of preparing the apartment for guests. She promptly prepared everything to accomodate all three of us, even though she was pressed for time due to work, she never complained about this last-minute extra task. Much appreciated!
The above is the only negative experience, though, as the apartment is very nice and comfortable and easily accomodates 3-4 people. Would definitely recommend it to others.
