The architecture is distinctly European, featuring grand, multi-story buildings with classic masonry. I see a sign that clearly reads "CURIO-HAUS" and another sign mentioning "Rothenbaumchaussee 30". These names strongly point towards Hamburg, Germany, specifically the Rothenbaum district. The style of the buildings and the street trees are very characteristic of this area. I am quite certain of this location.

Country: Germany, City: Hamburg.
Confidence: High.
