One amazing place to visit when in Berlin is a place about 1 hour train ride from Berlin city center called Potsdam. Don’t get confuse with Potzdamer Platz which is in the city center! While it is connected under the same S-Bahn line from Berlin, I just got to know later that it is in fact another city! Not a small one either, it is a capital of German Federal State of Bradenburg. It used to be a residence of Prussian King until 1918 and now it is the largest world heritage site in Germany.
Among interesting places to see in Potsdam are the Potsdam City Palace, St. Nicholas Church, the Old town hall, Glienicke Bridge and many others. But one of my favorite among all is the Dutch quarters where there are rows of nice small shops, cafes and restaurant. I went to one of the small café and they have a small nice garden where I can sit and enjoy my tea. To my surprise, the café is actually also the owner’s residence and they live upstairs. That has to be a dream job. To wake up in a nice quarters and work downstairs of your own house everyday ;-)
