This AirBnB is a genuine health-hazard. The listing does not have any pictures of the staircase, which is four flights of very narrow, very steep (at least 65 degrees) slippery wood with missing hand rails on the second and fourth floor. The rooms of the AirBnB are stacked atop one another, meaning the only way to traverse the space is via these stairs. However, the location is top-notch and if you are coming to Brussels for the history, this AirBnB dates to the 17th Century. But the price of this AirBnB versus the absolute death-trap of a staircase it contains is not worth the cost. Find somewhere else.
