Sure. These problems are Cairo's worst, but the city has wonderful lots to offer. And as you said, 2 midday is almost as 2 midnight: people in the streets, shops open and all are awake! lolAbout your title- when I was in Cairo I wondered when people slept because it seems like never, lol. There are many many incredibly beautiful things to visit but I was shocked at how dirty the city is. And chaotic. The traffic jams are a nightmare.
