The meeting point is between two cafes Les Blouses Blanches and Mon Café. We advise you to take metro line 8 and get off at Faidherbe-Chaligny station (2 minutes walk from the meeting point). The guide will be waiting there for you wearing a white shirt and carrying a leather satchel.
The tour ends in front of Column of July (Bastille square). The Bastille (line 1, 5 and 8) metro stations are easily accessible.
