More infos about Berlin taken from another thread:
Top 5 reasons why you should move to Berlin:
1. Lowest livings costs with highest quality of living. Stay in gorgeous, perfectly renovated apartments in pre-WWII residential buildings with high ceilings, right in the middle of the center and pay a fraction of costs of any other capital (even cheaper than any Eastern European capital). No need for a car—Berlin has one of the densest subway nets and wide streets make biking fun. In addition, Germany has an amazing social health care system including health, unemployment and pension (when working as an employee).
2. A vibrant and fast growing ecosystem of smart people. A vast number of new software talents, founders, software companies and VCs are moving to Berlin, every day (Twitter, Google, Soundcloud, Early Bird and many more).
3. People here are open-minded, outgoing, mix well and international—no need to learn German, everyone speaks English! Making new friends is a matter of days. Visit tons of networking and startup events, every week.
4. Easy work permissions—Europeans do not need any and can work from day one and the rest applies for the hassle-free Blue Card.
5. Berlin's night life is unmatched, huge and changing every day (plus ridiculously cheap). Berlin has got some of the most dazzling, naughty, and original clubs on the face of the Earth.
