For my last day in Istanbul I went to the Asian side, which used all the available means of transportation. Just about. There is great public transport and the Istanbulkart works on all of them. I took the faithful tram from the top of my hill. My apartment was on the main local street. But this is the old quarter and there is always lots of traffic.
The modern fast tram took me to the ferry port.
On the other side I took a historic tram to a quiet neighborhood where I had lunch and browsed antique stores. Took a bus back to the port. Then I went back in the train under the bay, which is fast and easy.
