This apartment is very spacious and well-appointed. We had no trouble accommodating a family of five. Having three bathrooms was a significant help. There is a generous kitchen/dining area, as well as three large bedrooms (one of which could be used as living instead).
The apartment is a short walk (5 minutes) to the very centre of Bologna. There are many cafes, restaurants, shops and sights nearby.
The only downside is that the apartment is above a cafe/bar. On two nights of our stay this was open until 3am, and the music and other bar sounds disturbed our sleep. I am not sure whether the hosts are able to do anything about this. Perhaps we struck bad nights, as no other reviewers appear to have commented on this.
