The "Lilly" drugstore sign is a very strong clue, as this chain is prominent in Serbia. The Cyrillic script on the adjacent "Герсна" sign confirms a Slavic country using that alphabet. The architecture, featuring large, utilitarian apartment blocks from the socialist era, is characteristic of Belgrade or other major Serbian cities. The presence of snow and the general urban layout point to a cold, continental climate. I am quite confident this is in Serbia.

Country: Serbia, City: Belgrade.
