The apartment was smaller than expected and is not *new*. On the other hand, it is cheap and right in the center of Brussels.
I wish the images would have been more up to date and shown the room completely. It is very small. There is only room for the bed and a wardrobe. We had problems opening our two suitcases. The bathroom in comparision is bigger. However, it's not perfectly renovated, at least from a German perspective :D
So, if you are looking for a central and cheap room, go for it. If you can spend a little more money, book a different apartment if you wish to have a bit more space and a newer apartment. A room outside the centre is no big deal, because the public transport is very good.
