The architecture of the large, blocky residential building with its specific balcony style strongly suggests Eastern or Central Europe. The graffiti on the curved building and the overall grey, overcast atmosphere point toward a post-Soviet or post-socialist urban landscape. The vegetation is sparse and dormant, consistent with a temperate climate in late autumn or early spring. I suspect this is in Poland, likely a residential district in a city like Warsaw or Łódź. I am moderately sure of this regional identification.

The street sign clearly reads "Kleine Pfahlstraße," which is a German street name. The architecture and the overall urban planning style are very characteristic of modern German residential developments. The overcast sky and the paved pedestrian-friendly area are typical for a German city. I am now confident this is in Germany, specifically in Hanover, given the street name. I am very sure of this location.
