There is not a single security point on the most crowded platforms of Istanbul, or a toilet for taking care of needs, or a health point for emergencies. There are 3/5 lines to each stop, there is no queue, order or security. In the cave layout you know, it's a wallet or phone stealing center for grabbing a seat.
It's very nice.But But the other day I decided to go to güngören for the first time in Istanbul.Believe me, I waited for 1.5 hours, and at the end I left, 97A someone is leaving, someone is coming, but 92C never came 😖
