The text on the blue doors says "Mehr Tempo" and "Mehr Beratung," which is German. The architecture is classic European urban style with stucco facades and tall, rectangular windows. The cars parked on the street are common in Central Europe. I suspect this is in Germany, likely in a city like Berlin or Leipzig. I am moderately sure.

The "Anfang" sign on the parking restriction pole is standard in German-speaking countries. The architecture, with its distinct rusticated masonry and arched doorway, is very common in older districts of Vienna, Austria. The house number sign (12) also matches the style used in Vienna. I am quite confident this is in Vienna, Austria.
