I have been there a couple of times in the past days, and unlike other times, many doors were open, and the girls presented themselves similarly to what you see in many houses in Vienna (an open-door policy, so to speak). However, I can't recall seeing a girl who looks like the one in Lena's pictures.
So, the girl who opens the door in her case probably doesn't look like the one in the pictures at all - unfortunately. However, this is just based on years of experience and visits to these houses, no evidence
