Berlin is the bomb!
If you like your history, drinking or partying in an authentic way then this is the place for you. Berlin has no airs and graces, its a real city with a soul and heart beat, its a little bit run down and dirty, but that was exactly what we loved about it. Whilst the centre is as you'd expect quite clean, corporate and touristy, visit other areas of the city (Kruizberg) and you will get a real experience, with quirky little bars and restaurants everywhere and graffiti covered walls.
Insider Tip:The holocaust memorial is certainly worth the visit and is just off from the Brandenburg gate and the Reichstag. The Berlin zoo was also pretty cool and killed a few hours, whilst I was waiting for friends to come from the airport.
Be warned, everything you have heard about clubbing in Berlin is true! It was apparent that 3 was the magic number, as we managed to get into Tresor and Watergate in 3's, after getting turned away on the Saturday and Sunday night when trying to enter as a 6.
