The signs use the Greek alphabet, clearly indicating I am in Greece. The architecture, with its multi-story apartment buildings and balconies, is very characteristic of dense urban areas in Greece. The text on the sign "AUTO SERVICE I. KOYPHΣ" confirms the language. I am fairly confident this is a Greek city, likely Athens or Thessaloniki.

The dense urban architecture with balconies and the specific style of the apartment blocks are very typical of Athens. The narrow, one-way street layout and the parked cars align perfectly with residential neighborhoods in the capital. I see a blue street sign on the corner, which is common in Greek municipalities. I am quite confident this is in Athens, Greece.
