My wife and I recently hired Menna for a tour of the Citadel, Pasha Mosque, Old Cairo and bazaar.  Our guide was excellent in every way, and was funny, personable and knowledgeable.  Menna's English was superb and she provided us with a proper historical background at each of our stops.  We highly recommend Menna as a travel guide.  Trust us, you will not be disappointed!  Kudos as well to Mahmoud our intrepid driver, who fearlessly navigated us between stops in the challenging Cairo traffic.
