The place is just as described. We were in Bologna during a hot spell and had good use of the balcony. We used the AC while sleeping and it works very well. Davide was highly responsive, even arranging a taxi for our departure. The restaurant below is good, there are much better restaurants in city center. The gelateria and pasticceria are both excellent.
Note the apartment is not far from the main square but you will likely walk back and forth couple of time a day as most of what you want to explore is that way. It is a nice pleasant walk and you sleep in a much quieter area.
