It's amazing how much info is in here. It goes through street by street, area by area. However you do get turned around quite easily because how it goes street by street. Would be great if they had a map on each page, or segment, that retraces the route they were just talking about.
I lived in Cairo for 6.5 years. The book made me wish I'd gone to see the tombs of Saqqara. I didn't even know there were tombs there!
