Just wanna drop my 2 cents for the Bologna apartment we stayed in...location wise is unquestionably convenient but only for people who travel without cars; with the implementation of zona traffico limitato, parking is a pain with the inconvenience of loading unloading luggages from afar. The apartment is two stories with bedroom upstairs whilst one might need climbing ropes to climb the steep and narrow staircase. The bed was cheap with springs you can feel on your back. Heater worked improperly with under heating most of the time. Electric water kettle was unwashed.
In short, if location is the only thing you look for, this might be your choice...
