I see a "SWECO" sign on a building, which is common in Northern and Eastern Europe. The architecture, including the blocky, utilitarian building and the snowy, wintery conditions, strongly suggests a location in a post-Soviet or Eastern European country. The Cyrillic-looking text on the building facade further supports this. The climate and vegetation are consistent with a cold, continental winter. I suspect this is in Bulgaria, possibly Sofia, given the specific building style and the company presence.

I am fairly sure this is in Bulgaria.

then: forward

The text on the billboard is clearly Bulgarian ("с най-добро на населението"). The yellow taxi is a classic indicator of Sofia, Bulgaria, as these are ubiquitous in the capital. The architecture of the residential blocks is typical of the socialist-era housing found throughout Sofia's districts. The snowy, slushy conditions match the winter climate of the region. I am very confident this is Sofia, Bulgaria.
