Kudy k La Residenza di Michelangelo

From the Train Station Santa Maria Novella:

Leaving the tracks of the train station, take the exit on your left, cross the road, turn to the right; when you get the corner (you can see a McDonalds), turn left; now you are in Largo Fratelli Alinari, that's the beginning of via Nazionale. Go ahead for 150 meters to the left of the street, there we are!
