I cannot recommend Andrea's place enough; we had the most wonderful stay. The location is amazing, just steps from the Due Torri and very walkable to the train station if you don't have cumbersome bags. The apartment itself has the most breathtaking views of lovely Bologna - when we weren't out exploring the city, we spent almost all of our time in the tower just soaking up the views. Andrea was also a marvelous host, even offering restaurant suggestions (Da Bertino is a must) and going out of his way to make reservations for us. We will definitely be back the next time we're in Bologna - five days was definitely not enough!
