For some minutes now I am sitting here and think what I could suggest to you - but there is such a wide range of things to do in both towns (Berlin and Munich) that it's hard to choose. Maybe you could tell us a bit more about your interests?

And concerning hotels - I only know "real" hotels in Munich, no apartment houses. In Berlin I thought I know one - but that will need more research, it seems it suddenly does not belong to the chain anymore it belonged a year ago. Would be rather convenient to Tegel airport and subway/bus, though not "central". So - what are your preferences for choosing accomodation?
