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.
Just an amazing cup of cappuccino. Try the Franzbrötchen with it for a basic breakfast. It's a place for someone who appreciates good coffee done with extreme care.
Beautiful atellier-stores around weserstrasse, this is from a very nice girl that make "sculpure hats" as she said. Excellent record store across the street also.
