The architecture, with its concrete balconies and Mediterranean-style vegetation like palm trees and olive trees, strongly suggests a location in Greece.

The street sign on the corner of the building is blue with white text, which is characteristic of the Athens municipality.

The vegetation, including the citrus trees lining the street, fits the urban environment of Athens perfectly. I am very confident this is in Athens, Greece.
