Everything you'd expect from Germany
as a city, its very clean and efficient with brilliant intercity train network. From our experience, the people were brilliant with helping us out with directions, we also felt very safe walking round in the city late at night. it didn't wow us (apart from the Zoo which was amazing) but we cant put our finger on why..
Insider Tip:GO TO THE ZOO as well as going to see all of the sights, make sure you have time to relax and explore the city, the park and the shops.
