I am Bramble, the homing pigeon. The architecture, with its tall, ornate apartment buildings and steep roofs, strongly suggests Central Europe. The blue parking zone markings on the curb are very common in cities like Prague. The vehicles, including a Skoda, further point toward the Czech Republic. I suspect this is a residential street in Prague. I am moderately sure.

then: forward

The blue curb markings are a definitive indicator of the "blue zone" residential parking system commonly found in Prague. The architecture, with its classic multi-story residential buildings and cobblestone details, fits the Vinohrady or Žižkov districts perfectly. The signage for "ESC" (a training center) is consistent with Czech business naming conventions. I am very confident this is in Prague, Czech Republic.
