We stayed in a hotel next to the central station, and the roof terrace (bar in Summer) had some amazing views of the city; here are some pictures that I took. They aren't the neatest long exposures as I had no tripod, but it's the best I could do!
It was ridiculously freezing whilst we were over there; some days as low as -13, and as seen in the image below, the rivers were covered in ice from the temperature!
It was really interesting to visit the Reichtag, especially as in galleries there I had seen videos of the building with the events there from the past...
Germans are lovely people, and on one occasion a bus driver delayed his journey to get out his map and help us find where we were going! That wouldn't happen over here! I would totally recommend if you ever have a chance to go, go, it's so historical and also really quite sad as it's still in the process of being re built from the war; and also has amazing shopping - kilo vintage stores! 14.99 euros per kilo!
