The image is upside down, but the architecture and the style of the street signs suggest a European city. The presence of a SEAT car and the general urban density point towards Spain or a similar Mediterranean country. The street layout and the dense tree canopy are characteristic of wide, historic boulevards found in major Spanish cities like Madrid or Barcelona. I am moderately sure this is in Spain.

The architecture, with its ornate, tall, historic facades, looks more Central European than Mediterranean. The street layout and the style of the buildings are very reminiscent of Budapest, Hungary. The white SEAT car is common across Europe, but the specific building style strongly suggests the Andrássy Avenue area. I am fairly confident this is Budapest.
