Extremely well situated : close to the train station and basically in the city center, everything at walking distance, and some nice places to have a drink and eat in the street itself. It can get a little noisy in the evening because it's close to a really nice bar, but when I was there it was calm after midnight and I had no problems to sleep. The flat itself is very clean and has everything you need. I only stayed one night before moving on with my trip but it was really an ideal situation. Would recommend and will probably try go back next time I'm in Bologna.
