By train to main train-station Munich and then take one of S3/S4/S5/S6/S8 to "Pasing"
and then take a Bus to "Dachstrasse" with Line 70. Walk in the direction the
bus is driving away :) and then next street left. Best to print out the link above.
The house is a bit behind trees and stuff. Look out for "ucrc"-sign.
