We had a very nice stay in Franca and Mario's apartment! They were very nice and helpful with tipps. Communication also worked very well (in English).
The apartment was really great and everything was nice and in very good condition (also bathroom and kitchen), it was also very clean. It had a parking spot in the yard, that was great as well.
It takes about 30 minutes by foot to the center, but since Bologna central station is literally just across the street, you could just take the bus.
All in all it was a great Airbnb experience!
