The house rents 126 rooms on 7 floors to prostitutes for a fee of 180 Euro per day, which includes meals, medical care, and the 20 Euro of tax that authorities collect per prostitute per day (including Cologne's "pleasure tax" of 6 Euro). The women come from many countries; about 30% of them are German. They typically sit outside of their rooms and negotiate with customers who wander the hallways. Some of the women live in their rooms, others rent a second room to stay in, while still others stay in their own apartments in Cologne.
