We weren’t able to personally meet Simon. It was Elvira who checked us in which wasn’t an issue.
The location is very close to the Rogier train station and/or bus stop which you can go to from Brussels Airport. We rode the bus (Bus 272) from Brussels Airport and it took us 45 minutes to the Rogier stop. It’ll be around 25 minutes only if you take train to Brussels-Noord then walk 10 minutes to the apartment.
The kitchen has complete amenities for cooking so it’ll be easy to prepare meals.
The living room and bed room were very comfortable. The toilet and bath are of decent size.
The wifi is fast but it doesn’t reach the room so much which will really push you to rest when it’s time to. Which isn’t a problem for us.
With that said, the apartment has more points for improvement: 1) That there are also toiletries that would be available for use; 2) Since the stairs is quite steep going up and there’s no elevator in the apartment, I hope you can also have the staircase aired out because it gets claustrophobic and does smell a bit; 3) Fix the wallpaper and other fixtures in the shower.
