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.

Cosmoveda is a hidden xberg gem. It's an Ayurvedic supermaket that happens to come with a kitchen with it. There you can find a delicious Ayurvedic lunch menu (with soup, main and a little dessert) in 3 different sizes, prices starting at just 5,90. Not to mention you can shop the ingredients that you just ate in case you want to try to cook Ayurvedic yourself.  

Cemetery of the Dreifaltigkeitsgemeinde (Dreifaltigkeitsfriedhof) in Kreuzburg on Mehringdamm 22, between Zossener Strasse and Blücherstrasse. The grandson of German-Jewish philosopher Moses Mendelssohn, is musician Jakob Ludwig Felix Mendelssohn who was born in Hamburg and lived in Berlin from age two. Felix Mendelssohn and his family are buried in the middle of Kreuzburg at the Cemetery of the Dreifaltigkeitsgemeinde. Today it is administered together with its 5 neighbouring Protestant cemeteries by the cemetery administration St. Jacobi number I.

A good place to drown your Berliner winter-melancholy. The bartenders are top notch and the interior is warm but stylish, with the inevitable retro vibe. Open from 6 till late. There´s also a legendary (and kinda expensive) restaurant next door, which provides the bar with some excellent snacks. Works for dates and for friends, but if you´re planning for a bigger group it might be wise to reserve.

It's an old entertainment park. It's closed now, but you can sneek in and see how nature has eaten the place up. Really nice to take pictures.
