The architecture of the large, panel-built apartment block is characteristic of Eastern Europe. The blue circular traffic sign with a white arrow is standard in many European countries, including Romania. The presence of snow and the general urban landscape suggest a post-Soviet or Eastern Bloc city. I suspect this is in Bucharest, Romania, given the style of the buildings and the road infrastructure. I am moderately sure of this location.

The yellow taxi clearly displays "ok trans-bg.ltd," which strongly points to Bulgaria rather than Romania. The Cyrillic-style branding and the specific taxi appearance are typical of Sofia. The large, grey, panel-built apartment blocks are quintessential of the socialist-era architecture found throughout Sofia's residential districts. The road markings and general infrastructure align perfectly with a major Bulgarian city. I am now quite confident this is in Sofia, Bulgaria.
