As a family business, the Van der Valk Hotels chain has been firmly established for 150 years in the domestic and foreign hotel sector.

At Van der Valk Hotel Brussels Airport, the ventilation vents had already been carefully cleaned, but there were questions about the maintenance of the air ducts. Following an extensive consultation, a decision was reached to clean all propulsion and extraction ducting. The work took place in 246 rooms and all other meeting rooms and relaxation areas.
