The architecture, particularly the style of the buildings and the cobblestone street, points strongly towards Central Europe. The "no entry" sign and the general urban layout are typical of Austria or Germany. The license plates on the cars are narrow and white, consistent with the European format. I suspect this is in Vienna, Austria, given the specific building aesthetics and street signage. I am moderately sure of this location.

then: forward

The architecture and the specific style of the residential buildings, including the external glass elevator shaft, are very characteristic of modern-era Vienna. The license plates are clearly European, and the overall urban density and street layout match the residential districts of the city. The sun position and the clear sky suggest a typical temperate climate for this region. I am quite confident this is in Vienna, Austria.
