Berlin, Germany I: Around Alexanderplatz

By the time I reached Berlin, I was burned out. I reached the hostel in the morning but my room wasn't ready yet.. so I glued myself to the sofa in the lounge and stayed there till 3pm when my room was finally ready. Then I took a shower and wandered around my neighbourhood. I don't know what I saw and honestly I can't say I've been to Berlin because I didn't see anything symbolic to Berlin, except the Alexanderplatz TV tower..
