Here are just some impressions of Berlin during the pre-christmas days. Many rushed to get last minute presents and some others enjoyed the many small christmas markets everywhere with Glühwein and Bratwurst and christmas music (http://en.wikipedia.org/wiki/Mulled_wine).
First three pics show Schlosstrasse in Berlin-Steglitz.
This one shows the artificial slide in front of the Potsdamer Platz station, where Paris Hilton took a sledge ride a couple of days ago..
And here's the nice inside of the Sony center...
