When I spoke to Wunneraum fur Studenten about 3 months ago for my start in August, they informed me that Eurocontrol students are quite far down their priority list. I was allowed to have a room till the beginning of October and then I would have to move out for 'proper' students.
Still, gives you enough time to settle down and make an informed decision on where to move on....... However i may have only been offered a room cos 'proper' students were on holiday, that may not be the case in February.
Best ring and ask them!
