I had a great stay at Michele's apartment. It is really perfectly located only a few bus stops from the train station and within walking distance to Piazza Maggiore. The neighborhood is also very nice with attractive shops and there are two excellent cafés and a supermarket nearby.
Michele's Papa is a very kind person and Check-in/out was very easy.
The only negative thing was the heat in Bologna during the weekend, which also heated up the apartment quite a bit. It has no air-condition but it has to be said this is not common in Italy, especially in older buildings.
