Good things first: Enrico is very friendly and flexible host and he communicates clearly and quickly. Check-in was easy and convenient. The location is one of the best ones in Brussels being next to the central railway station as well as the Grand Place. You can walk or go by metro/train/tram practically anywhere very easily. Neighborhood is safe and quiet and the apartment is nicely decorated.
What to improve: The bathroom is very small and we were unlucky to notice that it was in dire need of deep cleanse. Shower stall walls were full of white markings and there were dirt on the floor and seams. The living area floor boards made loud noise when we walked on them and it made us uncomfortable (we didn't want to disturb the neighbors). The living area was somewhat dirty too starting from the sofa with stains on it and dust in the room's corners. The stairs to the apartment are steep and narrow - we didn't have problem with them but I would imagine that an older person would, so reconsider if you have a disability affecting your mobility.
The place would be very nice all things considered if it would have been properly cleaned, if the floors were fixed and the bathroom was renovated.
