The architecture, with its distinct multi-colored facades and shutters, strongly suggests Central Europe, likely Switzerland or Germany. The street sign is blue with white text, typical of Swiss cities. I see a construction sign with a yellow background, which is common in Switzerland. The overall urban density and building style point towards a city like Zurich or Basel. I am fairly confident this is in Switzerland.

The street sign on the corner building is clearly visible and reads "Bäulistrasse". This is a specific street name in Zurich, Switzerland. The architecture and the "Stoppen für Schulkinder" sign confirm the Swiss context. I am very sure of this location.
