I stayed in Lulu's place for two nights, and I found it to be small (as advertised) but neat and clean. All the necessary amenities for a short stay were there, and possibly even a long-term stay as well (if you are fine with the size of the apartment). The place is located in a relatively quieter part of town, and was only a 10 min walk to Brussels-Midi station, which was convenient for me since the shuttle bus to Charleroi airport leaves from there. Lulu was also proactive in giving clear directions to her place and was responsive to my messages. Overall, I would say that the place has great value for the price.
