Kw is a great art institute situated at the backyard of a very eastern part of town, place for many other small galleries. Auguststrasse is worth the walk and Kw is worth the stop.
Chalet is one of many clubs in Berlin. It's a very interesting option if you want to know what Berlins night can be. Music is great and environment too. It 's a decadent building in the inside with curious corners...
Wim Wenders shot Wings of Desire here. It's a quiet place to work and definitely a gorgeous place to visit. Combine it with a visit to the Philharmonic, just across the street. Affiliation is 30 euros per year and you have lots of desks all over the library to choose from.
