Cafe, German, $$$
Close to the historical Checkpoint Charlie, Westberlin is a hip café with stable Wi-Fi connection. The perfect spot for early birds, who can start working during the week from 8:30 am. The café has a sleek, modern interior and a lovely collection of magazines in stock, so be careful not to get distracted. They have a range of speciality coffee to ensure visitors have a proper caffeine hit to keep working, and, if you need a vitamin hit for productivity, they also sell fresh juices that are full of the good stuff to boost your brainpower.
