I stayed with my parents for a couple of days in Paola's flat. It was very comfortable and super well located! By the way, Via Pratello is a great street with an amazing night life, full of bars and restaurants. And, even though the flat is located in this street, we didn't have problems with noisy, because the flat faces inwards the block.
Also, Paola was very attentive all the time and gave us lots of tips about Bologna.
