Coming from the main station, look out for the exit to Neuengasse, which will lead you to Waisenhausplatz. Cross over the square, looking out for the restaurant "Luce" and the shop "Office World," which will be diagonally opposite and to your left. Turn around the corner of "Office World" and you are in Nägeligasse. Continue walking and look for the entrance on your right with the sign "Evangelisches Gemeinschaftswerk, Stadtmission." Once inside the building, take the elevator to the third floor.
