Considering the El Mouradi Mahdia in Mahdia?

Medina by Willettsworld
Mahdia's medina is pretty small and fairly quiet. Most of its shops are located along Rue Ali Bey which is the main street that leads from the Skifa el-Khala. The shops are the usual tourist ones you'll find all over Tunisia. If you continue to walk towards the lighthouse you'll then find yourself in the narrow streets where there are some nice houses with nice doors.
