Honestly i were so excited too move from the small country area of Heidelberg,Germany to the BIG city of Berlin.until… i reached the rushed subways, repeating voice of doors opening and closing. And beer bottles in almost every hand
The place to keep your bag in the front of you and held with both hands at all time.and graffitti on all corners of transport links. Above all the busy life of berlin has many plus points,alot of people speak english and its very multicultural with good weather in the summer, and recycling without fail.
Hopefully these tips help you if you ever decide to move to the big city
