The architecture of this building, with its panelled facade and specific balcony style, is highly characteristic of post-war residential blocks found in Germany. The blue metal waste enclosure and the style of the entrance are typical for German "Plattenbau" or similar housing estates. The trees and the overcast sky suggest a temperate climate in Central Europe. I suspect this is in a city like Berlin or a similar urban area in Germany. I am moderately sure of this location.

The street sign confirms German language, consistent with the architecture. The paved walkway and the specific style of the building facade point toward a residential area in a German city. The autumn leaves suggest a northern temperate climate. I am quite confident this is in Berlin, Germany.
