I don’t know who needs to hear this (again), but Brussels’ Midi station (the only way to go into/from the city’s two airports* AND the Eurostar/Thalys) really, really sucks. Especially for women. Especially at night. And it’s been like this at least for over 15 years.

It does. And Noord isn't better.

Yes! I think it is the ropiest station I have ever been to. Why is it so bad? Don’t know Brussels very much but the rest of the city feels fine.
