The court is at the gym of the ATG (Allgemeiner Turnverein Graz) in Kastellfeldgasse 8, Graz.
To park your car in the surroundings of the gym (in the "blue parking zone") you will have to buy a parking ticket for Saturday from 9 am to 1 pm. Outside of this time period parking is free on weekends. If you park your car in the "green parking zone" parking is free for the whole weekend. However, you might have to walk a little longer (see the map of parking zones).
If you arrive by train, either take tram number three in direction "Krenngasse" or tram number six in direction "St. Peter" to "Dietrichsteinplatz", from where the gym is about a five-minute walk away. Tickets can be bought onboard the trams.

The party location is at the home4students (Neutorgasse 46), which is about a ten-minute walk from the gym.
