From Santa Maria Novella train station follow directions for the Duomo. Once you arrive at the Duomo take the road Via de' Martelli (Banca Toscana is on the corner of the street). After a couple of minutes you will come to a large brick building, you are now in Via Cavour. We are number 15, approx 40 metres from the tourist information point (which is just after the aforementioned 'large brick building')
