Nathalie and Claudio's apartment is very spacious and has a great view of the city. They had everything I needed for a short stay in Brussels, and I would definitely be happy to stay here again.
On another note, this area of town near the canal is perhaps not the most ideal for solo female travelers—a walk through this area alone at night is probably not a great idea. This is not at all intended as a criticism of Nathalie and Claudio's offer on AirBnb—I knew about this part of town before renting this apartment, and while the price, the apartment's proximity to the center/Gare du Midi, and the apartment itself are great, some tourists would feel safer in other areas of the city.
