The center of Mannheim is laid out like a chess board, with no real street names. Addresses in the Quadrat take the form of a grid reference, such as Q3, 12 designating a block. Note that the streets themselves are not named, rather "Q3" refers to the block itself. If you follow a street from Q3, you might end up at either Q2 or P3. It is best to navigate by "following" the blocks rather than the streets. If you get lost, a rather high probability, simply ask a local. They are used to it.
Mannheim was a small fishing village before it became a city at the beginning of the 17th century. It was constructed on the site of a fortress guarding the confluence of the rivers Rhine and Neckar. Even now a few remnants of the fortification can be seen, and the peculiar street layout owes to that part of its history. For 58 years, Mannheim served as a royal residence and gave Schiller, Lessing, Goethe and Mozart a home for some time. Before World War II Mannheim was a beautiful city, but was flattened in bomb raids due to its industrial significance. When it was time to rebuild the city, Mannheim, like many other German cities, opted for an all out modern approach to urban development. Thus, most of the old quarters were replaced by buildings typical of the 1950s. If you are not an adept to architecture, their appeal might not be easy to grasp. As a result, the impression is more of an industrial city with a few spots of beauty.
Modern Mannheim is the second biggest city in Baden-Württemberg and one of the hotspots of immigration. Because of that you'll encounter a lively and colorful mixture of nationalities and cultures in the city. The Mannheim/Heidelberg area hosts the largest concentration of US military personnel in Germany, and barracks are found in many of the suburbs.

The National Theater  has a different show almost every night (for some shows, like ballets or opera, the language barrier is not an issue). The street car stops right outside the theater, and student tickets are much reduced (5 or 15 euro).
 Stay safe
The most parts of Mannheim are safe, but there are a couple of districts that have higher crime rates. Examples are Vogelstang, Neckarstadt-West, Jungbusch (night) and some others. Street crime and violence, however, are very rare, so you will be perfectly ok if you simply use your common sense. In particular, it is not dangerous at all to visit the pubs and clubs of the Jungbusch or the Neckarstadt.
