Of the cities I’ve been to, Nürnberg/Nuremberg remains one which I remember as orderly—in the sense that the streets though with people walking is not crowded. You don’t get the feeling that you’ll be robbed and the streets are clean enough. That inside the wall, which has been built between 12th and 16th centuries. The wall run for 5 kilometers (about 4 kilometers still standing) around the old town. Inside are old buildings and churches, small bridges too. During our last visit, there were additional restaurants even a Starbucks integrated pretty well into the classic environment.
