The architecture, with its ornate, older European-style facades and balconies, suggests a city in Eastern Europe or the Caucasus. The vehicles are parked on the right side of the road, which is standard for right-hand traffic countries. The trees and general atmosphere feel like a historic district in a city like Odessa or Tbilisi. I suspect this is somewhere in Ukraine or Georgia. I am moderately sure of this region.

The architecture remains consistent with the late 19th-century style found in historic port cities of the Black Sea region. The dense, leafy trees and the specific style of the wooden gate on the right are very characteristic of the older residential streets in Odessa, Ukraine. The right-hand traffic and the general urban layout reinforce this location. I am quite confident this is Odessa.
