Good Questions: How Can I Liven Up My Hallway?

Hello AT,

Please help enliven my Hallway of Despair.

Blah. Narrow. Gray. Window-less.

It leads from our main stairs to the guest room and the back staircase (to the left of the guest room door).

The space is only 25 inches wide.

I'm looking for ideas for making this a warm, interesting, cheerful, clean space.

Thanks in advance for your suggestions!

Thanks! Jill
