The house is nice, but the layout is odd. The master bedroom is downstairs on street level, so the tram and school children wake you up in the morning. I gave up and slept in the 2nd bedroom which was small but much quieter.
The hosts act like they have an a quiet amazing house and welcome everyone, but they are actually total control freaks with cameras in the hallway to monitor you entering and leaving. They demand you make no noise in the hallway, yet all the neighbors stand and talk there which you can hear very clearly in the apartment. They emailed me almost daily asking if everything was okay which I found disingenuous and annoying (I was in Ixelles for work and didn't have time to be constantly communicating about what I was doing). Sure, the house is clean and looks like the photos, but after staying several Airbnbs all over Ixelles, I can assure you that there are as-nice and nicer apartments with much more relaxed and gracious hosts that are closer to Louise. Do yourself a favor and stay at one of those. Even if the hosts had been wonderful, I wouldn't stay here again, as it is far from Louise, and the tram and street noise made it too loud.
