This building (n°24) is currently entirely used by the "Fédération des Étudiants de l'Université de Liège", a student NPO associated with the "Université de Liège". Would be nice if someone could add that feature.
More info on that ASBL (🇫🇷): https://www.fede-uliege.be

N.B. : the website is currently under maintenance, will be resolved in a few weeks.
