I think this is a really İstanbul story and I suggest the visitor for seen in İstanbul with snow white. In night lights and historical places look like another perspectives. And some population is decreased in streets so feel İstanbul exactly for you.
PS.: If you see snow in İstanbul, be hurry because İstanbul change her white clothes with in two days.
