How to come to ETZ E6: ETZ ist the "Elektrotechnik" building of ETH Zurich, located at Gloriastrasse 35. It is most convenient to come by public transportation: Tram 6 from "Bahnhofstrasse" or "Central" (both near Zurich main station) or Tram 5 from "Bahnhof Enge", "Bellevue" (near the lake) direction "Zoo", exit at "Voltastrasse", walk a few meters back to the ETZ building (highest building near the tram stop). The room E6 is on the main entrance level E. If you come by car, either follow "Rämistrasse" from "Bellevue" upwards towards "Zoo" (turn right at the University of Zurich) or follow "Universitätsstrasse" from "Irchel" towards "ETH", "Universität", "Bellevue" (turn left after you passed ETH, in front of the University of Zurich). Then, you follow Gloriastrasse after around 100 m there is a left turn and after again 100 m there is a sharp right turn. In order to come to the ETZ building parking garage, you must cross Gloriastrasse directly at the right turn. Be careful, because you must cross the tram rails! To get access to the parking garage, you first must go to the "Hausdienst" at the entrance of the ETZ building on the E floor and tell them that you are visitor and need temporary parking.
