2 years ago we also booked a tour with Aziz in Tangier. We had a wonderful full day touring and at the end of the day he took us to our hotel and made sure we were all checked in and felt comfortable.
As previous posts, please don't be impatient with him. Many parts of the world do not operate on our hectic schedules.
He made our reservations on the ferry and picked us up at the dock. We were the last ones to be picked up and for a moment we actually almost panicked. There are several guides waiting for the ferry from Spain everyday and many asked if we needed a tour guide. When they asked who we were waiting for, we replied Aziz and they said don't worry, he was the best and would be there. Tangier is 2 hours behind Spain even though it is located directly south of Spain.
Aziz is very knowledgeable, takes you were you want to go. He speaks 4-5 languages and knows everyone in the medina. He took us into a friends home, so we could see how daily life is lived. We actually toured with him about 2 weeks after he had taken Rick Steves for a tour.
Enjoy your tour and relax. You will definetely not be in Kansas anymore. But take his cell phone number and email just in case. He has a Spain cell phone number and also a Morrocan one.
It was the highlight of our Spain trip.
