The blue rectangular sign with a white arrow indicates a one-way street, common in many European countries. The architecture of the buildings, with their simple, functional style, suggests a location in Northern or Eastern Europe. The overcast sky and vegetation are consistent with a temperate climate. I suspect this is in a Baltic country, possibly Estonia. I am somewhat confident in this assessment.

The architecture, particularly the style of the buildings and the wooden fencing, feels distinctly Nordic or Icelandic. The overcast sky and the specific type of vegetation are very characteristic of Reykjavik. The narrow, somewhat weathered street layout further supports an Icelandic urban setting. I am fairly confident this is in Reykjavik, Iceland.
