It takes about 10-15 minutes to walk down to Alexanderplatz, with the Tram it is one stop away. There are more beautiful places in Berlin, but Alexanderplatz is a commercial and logistic
center. And there are of course things to se and visit, for instance the revolving restaurant in the TV Tower. Rote Rathaus is here, where the municipal administration sit. And of course lots of restaurants and big warehouses. The smaller boutiques you find elsewhereø.
