 ::Perhaps :::Wilhelmstrasse (Wilhelmstraße in Germany: see ß)  ::is better. Stemonitis, is of course right that it is not only in Germany where this street name is Wilhelmstraße, but that might be a bit beside the point because in fact this street is in Germany so we should not need to mention how the name is written in Austria, say, in the lead. Again, this is not a terribly big point but I certainly think the ß link is useful.
