The architectural style of the stairwell is highly characteristic of Soviet-era apartment blocks. Key features include the two-tone paint scheme (mint green on the bottom, white on top), the poured concrete stairs with painted yellow risers/treads, and the simple, functional metal railing with a wooden handrail.

This specific aesthetic is ubiquitous in residential buildings across the former Soviet Union. Moscow, as a major hub, has countless such buildings and a diverse population, which would be consistent with the person in the photograph.

Cuba has a significant amount of Soviet-influenced architecture from the Cold War era, particularly in large housing projects like those in Alamar, Havana. The functional, concrete-heavy style seen in the image would be consistent with these buildings.

Furthermore, the Afro-Cuban heritage of much of the population aligns with the appearance of the person in the photo, making this a plausible alternative to a location within the former USSR itself. Several African nations, including Angola, had strong ties to the Soviet Union, which influenced the architecture of public housing projects built during the post-colonial era.

The simple, robust, and somewhat dated construction style seen in the stairwell could plausibly be found in a city like Luanda. This location would also be consistent with the ethnicity of the person pictured.

However, this is a lower confidence guess as local building styles can vary more widely.
