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.
A very good reason to travel West: the C/O, next to the formerly infamous Berliner Zoo tube station, is an awesome museum dedicated to photography and visual media. Previous exhibitions include Larry Clark, Martin Parr, Anton Corbijn, Annie Leibovitz and Stephen Shore.
Rixdorf is definitely my favourite area of Berlin, because it is a historic village within in Berlin. At the moment it is under heavy construction, and I found this strange, nearly taken-down building sitting in the middle of the quaint neighbourhood.
Berlin has plenty of magic cafés in every corner. This is one of them. It's quiet and it has a mixture of lights and furniture that really catches me. Cakes and coffees are also very tasty.
