Hi there!!! Frist of all viele danke meine susse Polizei!!! You have safed my life picking up me for the bus station dear, and actually safe my opinion about this part of Germany baby, because i was going to leave this city with such a poor mind about people there with no knowledge about any other countries and/or other languages!!! I was there on International Tourism Trades and btw. walked a bit in city centre seeing Reichstag, Branderburger Tor, Charlottenburg.. If the weather is sunny awesome view from Fernsehturm! The best book and music shop at FriedrischStrasse, to qucikly moving in the town use the train stations, dont take the buses and underground stops too often, too many stops :-) And on the ZooStation you can still meet drunk homeless people with drugs like that was 20 years ago The real Berlin.. hmm.. very hard city belive me! P.S. From Poznan, the city on the way from Warsaw - the capital of Poland to Berlin you can get for 20 euros by the inter city train in less than 3 hours!
