Berlin is a vast city with not one, but several centres that come in their distinct and varied flavours of cool. The fastest and most time efficient way to hit all the main attractions is to get on one of those hop-on hop-off buses. You can get a 24- or 48-hour ticket, as well as an option to upgrade to a river cruise boat. Buses run every 10–15 minutes. Of course, you get audio commentary in multiple languages, plus a kids' channel.

With the East Side Gallery, a segment of the Berlin Wall has been turned into the longest open air gallery in the world. The open-air East Side Gallery is located along the banks of the river Spree in Friedrichshain. At 1,316 metres, it's also the longest segment of the Berlin Wall that is still standing. Right after the fall of the Wall, this stretch was painted by 118 artists from 21 different countries. Using various techniques, the artists commented on the political events that took place in 1989 and 1990 in over 100 works of art found on the eastern side of the wall.

Berlin boasts the world's first computer games museum, which opened its doors in 1997. Since January 2011, the museum has been showcasing its new permanent exhibition in the fashionable Friedrichshain district. The exhibition has ingeniously converted the historic interior of the former East Berlin café, Warsaw, into a pixelated gaming landscape. It's the perfect spot to unwind, play some beloved video games, and delve into the history of the gaming industry. The Computer Games Museum is conveniently located on the Karl-Marx-Allee, the largest European cultural monument.
