Just saw a post by RS on Facebook earlier today that he landed in Istanbul for a week of research. Is he there now? We land on 11/6.
No, he was there earlier this fall and had a Monday Night Travel episode a few weeks ago where he described his trip. I watched because I loved my time there, and predict you will love it too!
He was actually there in mid-September (he left two days before I arrived :). Here is the Monday Night Travel show: https://www.ricksteves.com/travel-tips/travel-classes/monday-night-travel/fall-trip-report
I didn't see Rick when I was in Istanbul September 25-October 10, but I saw a small film crew about one block south of my hotel (which was west of Istiklal Caddesi in the New Town) on a couple of those days. It wasn't large enough for a movie crew. I didn't pay any attention to what language they were speaking--or even whether they were speaking at all. Now I wonder.
