Berlin – Museum für Kommunikation
So if you absolutely don’t know what to do on a sunday, I would suggest the Museum für Kommunikation. It is a great place for taking photos:
There are a lot of old fashioned stairs running up and down:
There are robots. The kids like to chase them around.
There are lots of ever changing exhibitions and at the end, there is quite a nice cafe to enjoy cakes and coffee culture from Vienna.
