Elena is a fantastic host with a great apartment. It is everything that you could wish for. It is 10 minutes walk from the train station and 10 minutes walk from the centre of town. It is silent at night and has the benefits of a lovely balcony to enjoy morning breakfast or an evening aperitif.
Elena will proivde you with everything which you will need to know (and plenty more besides) about Bologna.
I will be back and I will be recommending the apartment to friends.
