We had a wonderful stay in the apartment which was spotlessly clean and with the most comfortable bed ever! (It's right next to a church though, so don't expect a lie in when the bells are ringing!) There are no blinds (so be prepared for daylight early in the morning, and bright sun in the living room in the early evening) but this makes the flat feel really spacious.
The location was absolutely fantastic, only 15 minutes walk from the main strain station, and 5 minutes to Piazza Maggiore or the two towers (you have to buy your ticket to climb in advance), where the free walking tour (two hours) departs a couple of times a day. Basilica di Santo Stefano is definitely worth a visit and the walk up to Santuario di Madonna di San Luca via the covered porticos was well worth it.
There were loads of restaurants and bars within walking distance. We tried Osteria dell'Orsa (which we weren't impressed with despite the reviews), Breaking Toast (fab quick lunch!), and Baracca e Burattini (great food and music). Our foodie highlight though, was the Bologna Food Experience, a day trip out to see how Parmigiano-Reggiano, Modena balsamic vinegar, and prosciutto are made, along with plenty of food and wine tastings. They even picked us up from right outside the apartment.
