Diane’s apartment is the best Airbnb we’ve ever stayed at. It’s immaculately clean, very well equipped (quality washing machine, cable tv, high speed WiFi, etc), has an excellent location in close proximity (less than 3 minute walk) to laundromat (if you need to wash a lot of clothes quick or want to use the dryers), convenience stores, transportation (bus and subway), and one of the highest regarded restaurants in Brussels, and very spacious. This apartment is great for couples or families with a large bed in one room and bunk beds in another room.
Additionally, Diane is a great host. I can’t imagine you having any problems at her apartment, but if you did rest assured Diane would be very quick to respond.
