My office is in the CDA building in the old center of The Hague, at Buitenom 18. Don't be deterred by the CDA logo on the door, you are at the right place, just check-in with the receptionist.
By public transport > Go to Den Haag Centraal Station. Take trams 2,3,4 or 6 to the south, get off at Brouwersgracht, from there it's a 3 minute walk.
By car > First, set your GPS navigation to go to the Vaillantlaan, The Hague. When there, only then set it to Buitenom. The GPS systems do not take the free car zone in the city center into account and it will guide you the wrong route.
