For Istiklal, the course is consistently good. I've only seen a better course in this part of the city right next to the bridge. They did not ask for a passport, they did not take a commission. However, as in other exchangers.
A good exchange rate (compared about 10 exchangers for Istiklal, here one of the highest. On 05/07/2024 - 31.80 liras per dollar).
They didn't ask for a passport. The commission was not taken. The course corresponds to the posted one.
