I live near brussels south train station, which is also near the hackerspace (it's litterally across the street
). Last time, sliptonic and I think julian stayed at meininger brussels centre, which seemed pretty good, there is another meinigher one block away from home here. But it's all very close and easy to reach, only 2 or 3 tram stops away. There are more options too, if anyone needs help with stuff in Brussels, tell me!
I would propose we do some FreeCAD stuff around the FOSDEM, but if any of you wants to take a day or two to do some tourism around, there are a lot of pretty cool places to see (brussels itself, brugge, ghent... all within 1h distance) I'll be happy to come along and show you around.
