Oh, oh! I love FOSDEM. I live in Brussels and love the city, I want to make a couple of recommendations for people coming to visit:<p>1. DON'T RELY ON CARS. Traffic is awful here. Brussels is bikeable, has shared scooters and shared bikes as well as a fairly solid public transport infrastructure.
2. I recommend finding a hotel either in the city center, or near the Merode area (east of Parc du Cinquantenaire). Don't try to get a hotel near the ULB (the venue) itself... it's not the most exciting part of the city.
3. While you're here, take a moment to visit other cities in Belgium such as Mechelen, Leuven, or even Antwerp. They're a cheap and short train ride away (20 mins for Mechelen/Leuven, 40 for Antwerp).<p>Also if you have any questions feel free to ask them here I'll check back in a little while.
