In order to see and experience all that Berlin has to offer, one would have to stay for at least a week. Regardless of its quick and efficient public transport system made of trains (S-Bahn) and underground (U-Bahn), you might find yourself running out of time as Berlin's attractions are scattered all around the place. There's no time to rest in Berlin, though. After an exhausting day of sightseeing, a majority of tourists want to experience the infamous and edgy Berlin nightlife as well - it is nothing like the extravagant clubbing you get elsewhere in Europe.

If you're feeling stressed, slow down at one of the finest German beer halls or take a day trip to somewhere calm and serene to get away from the capital's constant buzzing. These excursions are easy to embark on and there is no reason to rush while there.
