Lucia and her partner were very kind. The welcoming was very charming. In addition, they told us a lot of info about the city (what to see, what to do, where to eat..)
About the flat. It is in a perfect location. You can walk to any place in the city centre. Also, the flat is 10 minutes by bus from the train station. There is a bus stop to the airport a 2 minutes walking.
The surround area has plenty places to eat and go out as well. So, if you want to come to visit to Bologna, this is your place.
