I'm ashamed to say that I have never been to Berlin, although have travelled around Germany several times. I have the opportunity to stay there for 2 days in October whilst my friend works, so need to have a definite structure for such a short time - I'm not usually a structured person, but needs must.
I want to see the Wannsee Villa and I suppose Checkpoint Charlie is a must, but where else? - Brandenburg Gate, Unter dem Linden????
I will have a good look in the Rough Guide as well, but personal reviews are always more helpful.
Oh, I've just remembered - my fav shops in the 80s were Peek and Cloppenburg and Kaufhof - still around?
