I recommend Ariana's place. it is not too far from the 'old' city. So walking distance and in a rather quiet one way street. It has all the amenities one might need for a short stay. You will not do that many cooking since Bologna is 'packed' with restaurants. But then again that is one of the three things it is known for: The fat.
if you come by train/airplane and do not want to walk to the apartment there is a bus stop nearby.
There are also some supermarkets nearby.
The apartment was clean and looks like the photos on Airbnb although to me: just a bit smaller 🙂.
But I can recommend this place.
