This is a great place to stay when visiting Bologna. The apartment is brand new and very clean. We were there when the weather was perfect (early September), but new AC units were available if needed.
The palazzo is on a busy street but because the flat is back on the courtyard we didn't hear any of the bus or motorbike noise.
The flat is within short walking distance of all major attractions—Due Torre, Piazza Maggiore, Mezzo Mercato, the university district—and shopping. We even had a nice walk outside the gates for dinner one night and it was only about 30 minutes. Tons of places to buy food to prepare at home, as well.
Alessandro is a wonderful host, available to answer all questions and provide help. He truly loves Bologna and wants his guests to thoroughly enjoy their stay.
Buon viaggio!
