Driving a car in Brussels is like listening to Mariah Carey’s duet with Westlife on repeat for a day: at some point you just want to kill someone (most likely yourself). Traffic rules don’t really exist here, which can come in quite handy when you want to park your car in the middle of the street, but it also make things more chaotic than the Koopjeshoek at Ikea.
You might think bicycling or riding a scooter might be the solution but the mentioned lack of traffic rules makes this quite dangerous. The safest option is to use the public transport. The maps are not that clear and it will be a bit hard to find your way at first but at least you will have all your limbs left.
Good tip: at most metro stations you have to check in and out, but you can take the metro from Brussels Central Station to Place Saint-Catherine for “free”. If you’re shitting your pants already, you can download an app called “Controle STIB” that shows you where the ticket controllers will be that day.
