The architecture, with its ornate, multi-story buildings, suggests a Central or Eastern European city. The presence of tram tracks and overhead wires is very characteristic of cities like Kraków or Wrocław in Poland. The red and white bollards are common in Polish urban settings. The overall atmosphere and the style of the buildings point strongly toward Poland. I am reasonably sure this is in Poland, likely Kraków.

The tram tracks and the specific style of the red-and-white bollards continue to strongly suggest Poland. The sign on the building on the right says "sady," which is Polish for "orchards" or a similar name. The architecture is a mix of historic, ornate buildings and modern infill, typical of central districts in major Polish cities. I am now quite confident this is Kraków, Poland. I recognize the urban layout as being near the city center.
