We enjoyed our stay in Bologna immensely. The apartment was easy to find, central, and keyless, meaning we didn't have to worry about multiple cards/keys. There were three bathrooms, which was great for three couples/families and Luigina really helped me out (e.g. put me in touch with a doctor when I was sick when I arrived and called us a taxi for our early morning flight). There is a coop one minute away and lots of restaurants/gelato within a few minutes walk. The centre is about 15min walk.
