Need to see what the stairs are like under the grotty carpet! Smarten up a hallway with a tailored stair runner. This narrow staircase has been made super chic framed, as it is, with wood-panelled walls and painted in on-trend pale grey.
Nantucket Entry by T. Keller Donovan, wainscoting on staircase, blue wall with family and sea art. I'd put a large port hole window at the foot of the stairs. Maybe a grey instead of blue and like this for the living room and hall.
