Panel at the stairwell showing that you are on the 2nd floor - parking structure at "Citadel Outlets". The wording is awkward at least in English and Spanish (I don't know about German) as "2" is above, not below the rest of the sentence; you can't finish a sentence with "del" in Spanish. The Chinese one is utterly incorrect. "水平" means "level" as in horizontal; the 2nd floor ("level" 2) would be "2楼" (or "二楼"), but "楼" in this context can't stand alone without a number preceding it.
