It's a small room in Anderlecht. Easy connectivity to the Brussels city but it is a bit far. You've to go up 4 flights of stairs. Wasn't very clean. The WC is again a few stairs down and is about 180cm in height so if you're taller you may have to duck when you get in.
The welcome was cold and someone who didn't speak English just handed me a key and left me to figure out everything else.
If you're out of options like I was, it is OK for a couple of nights but for the price I paid I felt it was underwhelming for sure.
