We had a great time in Maria's lovely apartment. It had everything we needed for our 5-day stay in Bologna.
Maria and her husband were very kind and welcoming and recommended all kinds of restaurants and sightseeing spots throughout the city. Their apartment is located a few streets away from a vivid nightlife area with great restaurants and bars, mainly visited by students and locals.
Located in the ground floor with windows facing the street, it's definitely not a quiet place. Still, the windows are well insulated, so if you don't mind sleeping with windows closed, it should be no problem (+ an air conditioner is available).
We can recommend staying at Maria's apartment and enjoying the great city of Bologna.
