Don't go to Munich and frankfurt.
Nothing is there to see. And propagnda w khallas.
معظم جمال المانيا فى المدن اللى محدش يعرف عنها حاجة
Go to Nurnberg - Bamberg - Rothenburg and heidleberg.. the romantic street starts from wurzburg and you can track it if you went to Rothenburg.. and Regensburg
I went to Berlin/Munich/Hamburg/Frankfurt/Cologne and they are ugly.
The above cities are the most beautiful.
