The driving is on the right side of the road, and the architecture and palm trees suggest a Mediterranean climate. The bus design and the urban layout are very characteristic of Spain. I see a tall, distinctive building in the background that looks like it could be in Barcelona. The bright, clear sky and vegetation are consistent with a coastal Spanish city. I suspect this is near the Avinguda Diagonal or a similar wide boulevard in Barcelona.

I am reasonably sure this is Barcelona, Spain.
