Commercial intermediary agencies are usually quite expensive. Be prepared to pay up to 3 times the monthly rent for extra costs, initial rent, security and administration charges. Room mediation agencies must have a licence that has been issued by the municipality. Any complaint you have about an agency can be submitted to the City Planning Department. For the addresses of commercial intermediary agencies: please refer to the Yellow Pages or visit the JIP in The Hague. Non-commercial room intermediary agencies are organisations which do not aim to profit from room rentals, as for example DUWO.
