I have Dreifarbenhaus and Leonhardestrasse accurately pinned on my map (URL below), as well as the "out of town" Waiblingen. I don't usually pin brothels like the fourth one mentioned, unless they are significantly windows and/or laufhaus-like. But other three are there.

Waiblingden prob too far for me so the other three will do nicely can't believe I missed two of them. Never mind. It's another excuse to visit beautiful Stuttgart. Time to check those maps.

How does Kernerstrasse4 work, last time I walked by it seemed shut, do you have to call to make an appointment or can you stroll in and walk around?
