Those cities are all located in Asia, except Istanbul and that is just barely.
“Those cities are all located in Asia, except Istanbul and that is just barely.”
Part of it, anyway. The other part is in Europe. The two are separated by the Bosporus. And there is quite the distinction between the two (at least there used to be, when I was there): The Asian side is older, dirtier, and more rundown; the European side is more modern, and somewhat cleaner (though still kind of cruddy by Western standards).
