I arrange this trip with 2 friends, and a friend offered us a place to stay there. We spend 5 days which was enough to see the most important tourist attractions in the city.
We visit several places, among them were the parliament, the city hall, the Brandenburg gate, Pergamon museum, Alexanderplatz, Radio tower, we also got the opportunity to visit the very impressive memorial concentration camp called Sachsenhausen, as a football fan I also visited the Berlin Olympic stadium .
It was a very nice trip to remember, specially because on the way back we almost lost the flight and we had to run a lot!!
