Love the cats! A bench is the right idea - but make it as wide as the window so that it looks almost like a window seat. If you can't find one the right size, custom benches are not really that expensive. Then how about a tall book case to the left, or possibly a wide demi-lune table with a lamp and some books on it. A runner in front of the bench would add some softness and color, but it looks like your hallway is large and has lots of angles so a runner might be awkward there... Good luck and have fun!

Beautiful area! As mentioned, I’d go with a custom seating area. When decorating, this area should be consistent with the tone; which is warm and cozy! See the photo below; this is the direction in which would incorporate a functional, but not overwhelming look. Happy Decorating!!! Houzz-“Digital Imaging by Tina”.

Flooring is fantastic...what type of wood flooring did you use?

I agree with a reading / seating area.

Love the picture from Digital Imaging! This type of look would be perfect for the top of your stairs.
