Berlin is a great city. In short: day 1 walk until feet hurt, see everything that you have heard of in the city. day 2 I tried to see what I missed before via U-bahn, tram, bus, S-bahn and walk a bit. day 3 visited concentrationcamp Sachsenhauzen. No words can describe that. Yesterday I went to the Olympic Stadium and saw Hertha BSC trash Borrusia Dortmund 6-2.
I had some great days.
Tomorrow back to work.
