Can you post a photo of the space?

I vote for wallpaper but for all four walls in an entry. So much more stylish and sophisticated than an accent wall.

Hallway

Which wall are you considering accenting? I agree that all 4 walls would look great with wallpaper.

Mirrored wall, but mirror being replaced by painting accented with sconces.

Painting, accented by sconces!

Wallpaper, all walls, no accent wall.

Thank you for your assistance, I concur to some degree however, one wall has a hallway entry, no way to make a clean cut for the wallpaper.

I see what you mean about a stopping point for the paper.. Perhaps a simple stencil instead of paper that could then be applied to all the walls.

I can't see the value in wood panelling. Looking at the photo, It seems like it is a little close and a little tall for that type of treatment.
