It's just not that convenient a place to stay when wanting to experience Brussels. The room was small, permanently hot so we ran the fan constantly with the window open and smoke would drift in from downstairs. The window was totally unsafe - we dubbed it the suicide window.
The area is dead, except for the atomium/mini Europe area which is overpriced, far too busy and we didn't go.
We were irritated by the lack of anything cold. There was one fridge downstairs which offered beers, coke and metal flavoured water for 2euros each. As a pregnant woman, none of these appealed.
The people were lovely and friendly always answering our questions and dealing with takeaway orders.
I would not go again, but if you're going for a specific purpose and know what you're doing, preferably in the winter, it's not terrible. And it's cheap.
