If you really want a picture of what it was like living with the Berlin Wall, this is the place to go. It's free, it's real and has both indoor and outdoor sections. The stories are written and in some cases have audio components. It's definitely a place I've gone more than once as there are so many different ways you can experience it: from just walking through, to reading every plaque to picturing yourself in someone's shoes. Really impacting and worth your time.
