I never heard about Havel until some friends and me checked out the google earth for a trip at the weekend. We went there in the german winter, oh yes...in the winter. I loved this place because is a small city island with a lake (which was frozen at that time) and with lovely houses and an old mill. I have never been there in the summer but i can imagine how wonderful would be.

It's a small bookshop to be stuck forever. Here you can find the most beautiful collection of art/photography/architecture/fashion/food books and magazines, not to count it's just a walk distance to diverse galleries around the neighborhood.

Volksbühne hosts and produces an intriguing program of theatre performances, contemporary dance and concerts. 

A very nice little second-hand bookstore, including a shelve with international books in French, English, and Spanish too. Always nice people to meet and a great selection of art and cook books, for affordable prices.

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.
