Kine Weekly wrote: "Sectacular war-time romantic drama turning on national enmity and embellished with song. The story seldom deviates from the obvious, but it covers an immense amount of colourful ground, is compelling in its love interest, and has the advantage of a first-rate cast. By appealing to the eye, the ear and the senses, it countenances no neglect of the essentials."[5]
The Daily Film Renter wrote: "Tullio Carminati is well cast as Toni, a role he enlivens with engaging touches of audacity. His handling of occasional songs is also quite pleasant. Lilli Palmer cleverly succeeds in making Gelda almost convincing, her work being particularly fine in the more emotional passages. John Garrick appears as Adolph, and the comedy is in the capable hands of Edgar Driver, who is never at a loss for some bright specimen of cockney wit."[6]
Picture Show wrote: "Tullio Carminati gives an attractive performance as the gay, happy-go-lucky Italian, and Lilli Palmer is delightful as the impulsive Austrian girl, Gelda... The settings are charming and convincing, and the photography excellent."[7]
Variety wrote: "Sunset in Vienna has a smattering of most of the ingredients thar go to make up a successful film.... Not a very original story, but its treatment is of a very high order."[8]
