The particular street signs, windows, and balconies on this street mark it as Parisian.
Paris, the city of light, is instantly recognizable—as long as you’re looking at a photo of the Eiffel Tower or the Louvre. But could you recognize the city if the picture lacked a flashy landmark? (Try testing yourself here—just don’t look at the text on signs.)
