I would totally recommend staying at Tommaso’s flat. It was very cosy, modern and clean, with lots of amenities. There is a restaurant called Ranzani 13 in the same building and supermarket Eurospin (7 minutes by foot), that is open from 8:30AM to 8:00PM. If you’re having a doubt, that the flat is too far from the centre of Bologna and right next to train line - don’t worry - we were staying at Tommaso’s flat for 4 days and there was no loud noises of trains passing by - actually I haven’t even heard any ongoing trains; now the centre is about 10-15 minutes away, but in a few minutes walking from the flat you will appear in the area of university, so you will be passing many ancient buildings, churches, restaurants and portics. Another thing we liked is Tommaso’s hospitality and caring. During these 4 days at his flat we haven’t had any problems or difficulties.
