The road markings and the style of the traffic signs, specifically the "no parking" sign and the blue pedestrian/cyclist sign, strongly suggest a Northern or Eastern European country. The architecture, including the limestone-like building facade and the modern glass structure, is characteristic of the Baltic region. The "100" sign on the building suggests a centennial celebration, common in Estonia or Latvia. I suspect this is in Tallinn, Estonia, near the Old Town or a historic district. I am moderately sure of this location.

The "Eesti Vabariik 100" logo on the building wall confirms Estonia. The distinctive modern architecture of the building on the right is the Museum of Occupations and Freedom (Vabamu) in Tallinn. The surrounding park and street layout align perfectly with the intersection of Toompea and Kaarli puiestee. I am very certain of this location.
