Berlin is the European city with the greatest development potential. Property prices and cost of living are very low for a cosmopolitan city. Berlin is “in,” Berlin is “sexy,” and is turning into the international center of attraction for creative- and service-providers. This vibrant city is one of the gravitational centers of politics and business in Europe. At the same time, Berlin has remained true to itself with its nightlife, its inexhaustible array of cultural assets, and its many recreational opportunities as the greenest metropolis in Europe. This unique mix allows Berlin the potential to close the gap to other big cities, such as London or Paris.
