Mr. Abdelkarim Touati was recommended to us by a Tunisian colleague.
His knowledge of Phoenician, Carthagian, Punic, Roman and more recent Tunisian history was encyclopeadic and well presented. He is also a member of the Tunisian historical/Museum society and multi-lingual.
His English was excellent.
He is a runner, so we chose to tour Carthage and the Carthaginian & Roman cultural and historical sites on foot - also highly recommended. He was just as willing to lead a bike or taxi-between-sites tour.
We started the tour knowing a reasonable level of Carthaginian history and left happily knowing a great deal more.
Being in the the context of the physical Carthage with an historical and cultural expert was an extra-ordinary experience. He was able to dive deeply into history and culture as requested - which, of course, we frequently did.
Abdelkarim's tour leading style was friendly , communicative,very interesting and inclusive.
