Meet just inside the lobby of the Al Attarine Madrasa. Hotels and traditional riads are scattered across Fes' old medina, and the Al Attarine Madrasa sits in the centre making it walkable from most. Here's a pre-filled Google Maps link to our meeting point https://maps.app.goo.gl/znXnQ5y4xzMiftWW8
The tour concludes at the Platz El Mokhifa. Though this is still in the medina, it is next to a taxi rank should you need to take transport back to your hotel or riad.
