I'm planning a trip to Turkey in October. I'll spend 3 days in Istanbul, then fly to Cappadocia for 3 days 2 nights. From there on, I'm trying to find a local travel companion to take us to Nemrut, Diyabakir, Mardin, Midyat, Urfa and Harran (5 days, 4 nights). I've been reading about Diyabakir being a dangerous city, both because of crimes and the poltical situation. Should I avoid the city? Just take a tour on the city wall? Is this city really worth exploring considering the safty factor? Or should I just bypass it and devote more time to the other places mentioned above?
