We had a great stay of 4 days in Carlo's studio in Bologna. It's a renovated wine cellar that looks as good as shown in the pictures. Carlo's father Sergio met us when we arrived, helped us with our luggage, showed us around, and suggested sites in Bologna to see. The day we left, he arranged for a taxi and helped us with luggage again. The apartment is nicely furnished and very clean. A few of the other reviewers have commented about the musky smell: it is a cellar, after all, and even has an old water well (oh and an old clay pot displayed under glass in the floor). But they provided a dehumidifier, and by running it and the a/c the musky smell goes away very quickly. We have no hesitation recommending Carlo's studio to fellow AirBnB'ers!
