I know we all have different perspectives, but after Beijing and Shanghai, I found Berlin's subway system very confusing and difficult to navigate. I found the signs vague and it took a while before I worked it out. Some extra signs to direct us to major stations like the Hauptbahnhof etc, would be useful. Connections are also not clear as in other cities. It may be fine for the locals, but as a short term tourist, I'd like to see a little more clarity with more directions displayed. Has anyone else had a similar experience?
