The architecture features classic European multi-story residential buildings with ornate facades. The road markings, specifically the dashed line for parking and the "ZONA 30" sign, strongly suggest a German-speaking country or Spain. The "ZONA 30" sign is written in Spanish, pointing towards Spain. The dense, urban residential street layout is typical of many Spanish cities. I am fairly confident this is in Spain.

The street signage, particularly the blue parking sign and the specific style of the street name plate on the corner, looks distinctly Central European rather than Spanish. The architecture and the overall urban atmosphere strongly resemble Prague, Czech Republic. The red-and-white street signs and the specific style of the building facades are very characteristic of the city. I am quite confident this is in Prague.
