If you're looking for a professional guided tour by a profit-driven company that blasts you with information for 3 hours and then says goodbye, this is not the tour for you. Instead, we got an intimate tour (my friend and I, plus one other couple) during which Saber told us about the history of the places he was showing us and patiently (enthusiastically, even) answered the million questions I had, many of which were about the Arabic language and life in Tunisia rather than what he was showing us. The tour ended up being a lot longer than 3 hours, but we had great conversation the whole time, experienced things we never would have otherwise (like taking a minibus), and ended up having tea/coffee at a café with him. If you're looking for an intimate tour with a very friendly and helpful local, I would definitely recommend it! It is advisable to bring some Tunisian cash for the minibus and museums.
