Once you have parked your car outside the medina, Avenue Habib Bourguiba is the best place to park on the left side of the road, you enter through the main entrance of the Medina. The main entrance is the one on the Av. Habib Bourguiba with on the left a shop that sells fresh juices.
Go straight away and pass on your right side the BNA bank till you arrive on your left at number 112. Exactly there at your right side you have Impasse number 7. My house is the last one with a yellow door on the left.
