learning French in Tunis

Hi
I'm new in Tunis and here for 3 years as my wife is working for The African Development Bank.
I am looking to improve my French which is basic and wondered if anyone new of a school or courses in the Central Tunis, Carthage or La Marsa areas.

I would also consider exchanging French lessons for English lessons. I taught English in Brazil in the Protected content , if anyone was interested

Thanks for your help.

best wishes

Mark
