We enjoyed our stay at Valeria's recently renovated appartment a lot. Everything is brand new. Location on the piazza is perfect, near the train station and at the beginning of the nice main street leading to Piazza Maggiore (Via dell' Indipendenza). The view is great indeed. You can eat on the balcony in the sun at night :).
Valeria was a good host, gave us directions about where to park the car and to find a supermarket nearby. Valeria was flexible about when to meet us at the apartment and kept in touch whenever neccessary.
We will definitely return on one of our trips to Bologna!
