I'd like to decorate my hall soon, so I'm looking for wallpaper. Unfortunately, the hall is really small and quite narrow, no windows and 7 doors leading off it. As there isn't any natural light or much space,I don't think I can really go with anything too patterned, bright or bold  But don't want anything too bland either. Any suggestions? It currently has a grey carpet, but I'm thinking I might swap that for wooden flooring and then just add a rug.
