Pros:
The location is just so great. You can access the main attractions in Brussels on foot.
The living room is spacious and bright. The kitchen is quite good.
Cons:
The bathroom is old and sometimes, while we take a shower, the water temperature just changed from warm to very cold. There's no curtain in the living room, so if you need to sleep on the sofa bed, you may need an eye patch if you can't sleep well with the light coming through the windows.
