This is an absolutely great local find! It’s obviously someone’s private apartment and you can tell that he takes good care to make it comfortable!
The shower room is separated from the toilet room to give a bigger feel for groups and there’s a washer and dryer for only 5€ right in the unit.
I really liked how everything was clearly labeled from the locks to the cabinets. I also personally loved all the international adapters and usb outlets.
It is walking distance to everything in the city center. I really doubt you will find a better deal in Brussels for a four bedroom.
