The presence of tram wires and a bus stop suggests a major urban center in a country that drives on the right. The style of the buildings and the overall atmosphere strongly point towards Budapest, Hungary. I am quite confident this is near the Danube riverfront.

Country: Hungary, City: Budapest.
Confidence: 85%
