Okay, so my comment was more a joke than a recommendation. But there is a truth to it. Berlin is generally known as an ugly and dirty city. In addition, Germany is one of the very few countries where the capital costs more money than it generates. But there are obviously still interesting and beautiful places, especially since Berlin has a rich history. And fun fact: even though the wall has been (mostly) gone for quite some years, the city is still pretty devided. For example when looking at the city form above at night, you can see the different street lights. And more importantly, the difference can also still be seen in elections, in Berlin and Germany as a whole.
