By public transport: take tram number 7 or 15 from Central to Sonneggstrasse (two stops). Then walk for approximately 50 metres in the same direction as the tram until you reach Sonneggsteig, a long flight of steps to the right. Climb the steps and turn right at the top. The third building (white with green shutters) is the Human Resources department.
Travel time: approximately 15-20 minutes from Zurich main station to Turnerstrasse 1.
