For all those selected, I believe your current concern is finding accommodation in Brussels. So I decided to start this topic, in case anyone has useful housing links/offers/advice.
I am in the process of securing a rent agreement with someone recommended by a friend. As far as I know, it's a two bedroom apartment, available for the duration of the traineeship, very close to the EU area (not yet sure where exactly). The rent for the entire apartment is around 600 E. I would therefore be keen on sharing the apartment with another girl doing her traineeship at the Commission. If interested, please send me a private message on this forum with some details about yourself, and I will contact each of you with more information about the apartment when it becomes available to me.
