Monochrome chic. Simple is best 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.
Dart Midnight Blue stair runner from Roger Oates #StairsandStripes Love this runner. Carpet on stairs is very important to me for safety. Do not want hard wood or laminate stairs. But there is already carpet cut into stairs so replace. Love this look and the colors.
