From the highway A1, exit at "Firenze Certosa" and, after paying the toll, turn right on the "superstrada" towards Siena until San Casciano exit; go on for about 4 Kms and follow the indication for "Teatro" and "Museo". Stop in the main square, "Piazza della Repubblica" and park the car. The B&B ART is beyond the ancient walls on your right.
