The street features tram tracks, which is common in many European cities. The architecture, with its ornate, older buildings and specific street-level retail, strongly suggests Central Europe. I see a "SPAR" sign, which is very common in Hungary and Austria. The overall urban layout and the style of the buildings look very much like Budapest. I am fairly confident this is Budapest, Hungary.

The tram tracks and the specific architectural style of the buildings confirm Budapest, Hungary. I see a sign that says "LAKBERENDEZÉS," which is Hungarian for interior design. The street layout and the presence of the tram lines are characteristic of the Grand Boulevard (Nagykörút) or similar major streets in the city. I am very confident this is Budapest.
