I'm only giving this museum 3 stars, because there are so many world class museums in Berlin. 1st, it may be small, but it's right next to Checkpoint Charlie, so you might as well go, 2nd, small though it may be, it is well structured and very informative. They also have a nice gift shop situated at the way out, where you can buy actual pieces of the wall. Solid 3 stars, but I'm grading on a curve.
