Our stay was not as good as we expected because of outside noise. All 3 nights there were people making noise in the street at 3 in the morning. Considering the apartment only has 2 windows facing the street having more modern double glazed windows wouldn't be such a big investment and would really change the apartment completely.
The apartment itself is nice and spacious. I wouldn't recommend it for a long stay as it doesn't have a washing machine and I really missed a microwave which is quite common in all apartments. In its current state if I went back to Bologna I would choose another apartment.
