From Stuttgart Hauptbahnhof (main station) you can take 5 different local trains: U 6 going to Möhringen, U 5 going to Leinfelden, U 7 going to Ostfildern, U 15 going to Fernsehturm and U 8 going to Nellingen. Get off at OLGAECK (3rd stop) and walk about 50m up the hill, then turn left onto Alexanderstrasse. After 30m our hostel is located on the left side of the road.
