This image depicts a long, empty, well-lit corridor. The corridor has white walls, a suspended white tiled ceiling with recessed lighting, and a light-colored tiled floor. The floor is bordered by a black skirting board. There are illuminated vertical light features embedded in the walls at intervals. Further down the corridor, doorways or rooms are visible, along with some signage. The scene appears to be indoors, possibly in an office building, hospital, or institutional setting. The perspective suggests the photograph was taken from a standing position, looking down the length of the corridor. There is no indication of the location being in Sofia, Bulgaria.
