Hi, I doubt that "Post Box" is actually the NAME of a post box in Erzherzog-Karl-Straße. Are you sure there is even a post box where you entered it, because there is one mapped right on the opposite side of the road too?

Also I don't think there is an INTERNET CAFE in the middle of the Schönbrunn zoo. If the zoo has free wifi, it should be tagged internet_access=wlan, not a node created somewhere in the middle.
