Berlin is dead cheap. Cheap flats, cheap office space, several universities with CS programs, a laid-back life style, good living quality in many of the inner districts.
dead cheap is getting more and more to "starting to get expensive". Prices are rising so much the last years, especially in Kreuzberg and other cool places. Offices are also getting more expensive and harder to get. Currently looking for a nice and affordable office in Schöneberg... :(
I think it's time for killing the "Berlin is dead cheap" myth
Even though Berlin is not as cheap as it was a few years ago, it's still much cheaper than other big cities with a comparable tech/startup scene. Ever tried to rent in London? New York? Silicon Valley? Even Munich or Hamburg (and I'm not claiming those two have even remotely comparable tech scenes)? Compared to these places, Berlin is still cheap.
