This is an excellent place with a great location. It is extremely roomy, even by American standards. With a major tram line right outside, you can quickly get around Brussels, and many major sites are in walking distance. The kitchen was well enough equipped to bring back food an eat there. The beds were very comfortable.
The views of the plaza were lovely. It was like living in a storybook!
My only qualm was that the stairs are rather steep and for about the first third there is no railing. This presented some difficulty for a member of our party with knee issues.
