This is a rough plan I have for our trip.
Monday- Since we are staying in Kreuzberg I would like to walk around the area and have a look at shops etc. I will go to a Graphic Novel bookshop which is Oranienstraße 22. http://www.modern-graphics.de/wir/ not the best one I recon but I read they have a good variety of books.
For those who are interested in German food http://www.maxundmoritzberlin.de/ which is Oranienstrasse 162 Kreuzberg . It is an original german alehouse.
Tuesday- Is dedicated to museums. Bauhaus museum http://www.bauhaus.de/index+M52087573ab0.html
Jewish Museum Berlin http://www.jmberlin.de/ jewish culture in relationship to Gemany.
The Wall Museum http://www.mauermuseum.de/english/frame-index-mauer.html
Wednesday- Filmmuseum http://www.deutsche-kinemathek.de/
Afterwards I will have a look at second hand shops Prenzlauer Berg.
Thursday- Someone posted it before ... I've never been to Tacheles which is a squat in Berlin. http://super.tacheles.de/cms/. This link might be helpful as well. It is an article about squats in Berlin. http://www.guardian.co.uk/travel/2009/jul/12/berlin-squat-music-food-parties
I try to see as many as I can.
Friday- Shouldn't be too stressful. I would walk around Prenzlauer Berg and Kreuzberg and might visit galleries or museums that I couldnt see the day before.
The plan I made is still quiet open which leaves time to explore Berlin
