Neither, it is bigger and ceilings are higher. And the building isn't standard concrete panels (the shape of the window and the thickness of the walls in the window opening in particular tell that). So, it is older than Khruschev. May be Stalin time or pre-Revolution (elongated shape suggests not original design and instead ad-hoc space reorganization that happened to pre-Revolution flats when they were made into multi-family "communal" flats).

The apartment building in the movie is of the "improved" design, very infrequent type of building at the time, and typically the kitchens there were a bit larger. The kitchen in the movie isn't real though - such large kitchens never existed in post-Stalin mass built multi-story apartment buildings. I've seen such large kitchen only in the Stalin time built 3 story building where top city officials/bosses lived - my friend's father was a CEO of a factory, and so they lived in a flat in that building.
