love the wall color! A rich cocoa makes the small entryway seem grand. Black semigloss paint on the railing and accents of crisp white create a bold contrast, one of the keys to livening up a neutral palette.
Simple in a narrow hallway. White painted stairs make them appear wider and the grey runner is both practical and elegant. Seek out a slim console - vintage or modern - thats useful and decorative but not space-consuming.
