We had a great stay at Maria's. The flat is very comfortable and immaculate, although two more comfortable chairs in the sitting area would be nice so that everyone chan chill after a long days walking. Finding a place to park might take a little circling, especially if you arrive in the evening. It costs €1.50 p/h from 8am-8pm, so make sure to bring plenty of change. As we didn't have enough change with us we just risked not paying, as a guy we asked had told us that the tickets were around €25 and they don't come everyday...we were lucky....unless they do paperless tickets and we don't know yet that we got one. We walked the 20 Mins to the Duomo each way every day, very straight forward. Maria is very kind and helpful and if you don't speak Italian Google translate can help to communicate.
