From the A1 highway:
exit at Calenzano. Turn around all the roundabout you find in front of you: you have to take the road on your left.
At the second little roundabout take the third exit (via Baldanzese).
In a short time you will see the road turning left. On the right you will see a grey gate: it's the entrance to our warehouse, that is the last one in front of you on the left.
