Cairo was really good and I enjoyed my trip there. since tourism is low there traffic was somewhat bearable. I believe it is safe to travel to Cairo and the political situation is under control.
Insider Tip:since very few people travel Egypt it is the best time to travel if you hate waiting in line or sites. and the prices for a lot of things are easy to bargain with due to the fact of low tourism. I would suggest you travel now if you're the bargain traveler.
