TL;DR: fast internet, many sockets, entrance room is pleasant but tiny, side rooms have no music, good for 1-3 work hours

This small neighbourhood coffee should have be a hidden gem. However, the coffee is mediocre (as opposed to what the name implies) and the big side rooms have no music, so sitting in one of them is as fun as working alone in an office after hours.

On the good size: internet is really fast (for Berlin), while there are enough sockets available. The tiny entrance room (five tables) has pleasant chilled music, and as long as you don’t mind sitting under the eyes of the bartender, that’s a good spot.
