The architecture of the tall, grey residential blocks is characteristic of Eastern Europe. The presence of tram tracks in the middle of the road and the specific style of the bus stop/kiosk suggest a city in Romania, likely Bucharest or a similar urban center. The Cyrillic-adjacent or Latin script on the billboard and the general layout point towards a post-Soviet or Eastern Bloc influence. I am moderately sure this is in Romania.

Country: Romania, City: Bucharest

The text on the billboard is clearly Bulgarian ("Без аналог", "в борбата срещу стрии и целулит"). The yellow taxis are iconic for Sofia, and the tram infrastructure confirms this is a major city in Bulgaria. The architecture of the residential blocks is typical for the socialist-era districts of Sofia. I am very confident this is in Sofia, Bulgaria.

Country: Bulgaria, City: Sofia
