My wife and I stayed at Franca and Mario’s Casa Mamma. The location is perfect for accessing trains for day trips from Bologna. Franca and Mario greeted us upon arrival and gave invaluable information; they made us feel welcome and comfortable. Later, Franca and another guest came over for a nice visit, it was a pleasure. I highly recommend staying there, especially if you are planning day trips outside the city. My only warning is that the upstairs occupant stays up late (typically past midnight, one night until 3 AM—we’re they moving furniture?) and because of the hard floors, any movement is loudly transmitted into the apartment, especially the sliding of the chair and closing cabinet doors—fortunately they didn’t seem to be wearing hard shoe soles, so that was a blessing. But the late night activities were not conducive to a restful sleep. Aside from that, we really enjoyed our stay; it was extremely comfortable and a good place to relax from the high-pace of sightseeing.
