Centenary celebrations for Belgrade's Hotel Bristol

Celebrating the centenary of Belgrade's Hotel Bristol, Predrag Najdenov, Front of House Manager, sends these early pictures. The hotel looks hardly changed at all from its bright beginnings. The neoclassical building was designed by architect Nicholas Nestorovic and enjoyed a few brief pre-war years when the Serbian and Austro-Hungarian monarchies set the social pace in the city. In 1924 the exiled Zog of Albania lived here. Today, the two-star hotel is a protected building. Its 62 rooms and suites include the luxury Rockefeller apartment. See their website.

Where in the world is this Hotel Bristol?

Roland-François Lack, who runs The Cine-Tourist website has emailed this image of the Bristol Hotel from Cloak and Dagger, starring Gary Cooper. In the film, directed by Fritz Lang and made in 1946, Cooper plays a spy who flies to Zurich. "Everything is shot in Hollywood," says Roland-François, "but there is a brief shot of stock footage showing a European-style street with a Hotel Bristol."

He says he spent a "very enjoyable morning" here on the Hotel Bristol Site, but still could not find it.
Well, no, this one hasn't come up before and there is no image of it in the extensive Hotel Bristol archives.

The hotel is clearly not the present Hotel Bristol in Zurich (pictured below)

So where in the world was this hotel? The shop sign beside the hotel is not legible, but the figures above the store may be a clue.
