...and it works!
The central ‘Mitte’ area of Berlin is packed tight with galleries and museums, which means you can cram a lot into a short amount of time, if that’s what you want.
The best of the lot is the Me Collectors Room, which shows off large chunks of the Thomas Olbricht collection alongside other contemporary private artworks. The permanent ‘Wunderkammer’ display offers over 200 pieces from the Renaissance and the Baroque periods, with a solid focus on the strange and macabre. There’s even a Mark Ryden original that fits in nicely.
There's nothing more revigorating during the dark winter days than spending a couple of hours in a sauna. Germans have mastered the art of sauna and you can find amazing pieces of architecture in the public swimming pools (Stadtbad). I find Stadtbad Neukölln very peculiar in its neoclassic architecture and it's definitely a wallet-friendly option to enjoy some sauna time there. Be prepared to be naked in front of man and woman!
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.
