You must reach the medina door Bab Laksour, take a porter if needed (he knows Magellan) and enter the old city walking on Sidi El Yamani Street. After 300 meters at Café Bougainvilliers, turn right and after 50 meters on a little plaza, take the 3 steps of a little stair on your left. You are on Magellan little street. Take a right just before Riad equity Point and go straight. You are at Magellan.
