there are "private houses" on the roads between Belgian towns Sometimes the ladies are sitting in the windows in evening dresses or lingerie, but usually you can spot these establishments by their large lace curtains over their windows, their large parking lots, and the distance between them and another building.

There are smaller private houses in the cities, usually as discrete apartments with just a few girls working in them.

There are also independents and agencies. Speaking French helps.
