Brussels is an amazing city! I went there for a whole weekend with my friends who are exchange students as well. We did two hop-on-hop-off-bus tours and saw the most important sights like the EU parliament, the king's palace, the Atomium, etc. I fell in love with this city due to the nice infrastructur, architecture and the good atmosphere. And of course, we enjoyed the famous, delicious belgian waffles and chocolate too. :-D It took us just three hours to go there by bus. I will definitely come back again! :-)
