Overall: 5-Stars...would absolutely recommend and personally stay again.
Pros: This location really can't be beat, especially for what you pay. It is extremely close to the Brussels Central Station and many things to do and good places to eat. Soap and shampoo were provided in the bathroom which was a nice surprise! We didn't have the time take advantage of the kitchen amenities, but I still took a look and they were very nice. There is also a "receptionist/door attendant" who is there from 8am-9pm always willing to assist you, whatever the need be.
Cons (these are small things to me but may be important to others): It can be a little loud at times due to pedestrian traffic outside and other guests staying in the same building (walls are thin). The entire unit was a bit smaller than expected, but not so small that we were uncomfortable.
