We were in Bologna just for a day, and stayed in this B&B for a night. Even though reception is not 24hours, owner was really nice and hospitable, giving us advice on where to go and all (even keeping our luggage for us till late at night the next day). While the place is not exactly central located, it is just a 5-minute walk from the other side of the train station. Walking to the city centre is easy too. No aircon in rooms but there is wifi, TV, fridge and everything is clean. Interior is lovely too! Excellent value for money.
