We spent four great days in Bologna. Mattia's appartment is very spacious and perfect if you're five people or more. And it is very central. I think you can't get more central in Bologna. Just some steps between Piazza Maggiore and Basilica di San Petronio and the two famous towers. The communication was very easy. Sandra welcomed us, showed us around the appartment and gave us the keys. One small thing. In the rooms facing the street it can get a little bit noisy in the night as you are in a lively street and the windows are not that "sound-proof". But next to that - perfect stay. Thank you Mattia.
