The apartment is good and as all the necessary features, in particular the wifi is of good quality.
The location is alright: a relative short walk to the city centre of Brussels (I would say around 15-20 minutes) and Also right next to a train station (Gare du Midi), which gives access to the underground making everything in Brussels easily reachable.
The hosts are friendly, we enjoyed our stay very much!
In short, the apartment includes all the features for a comfortable holiday, the location is alright and the hosts are friendly.
