Hi there,

How about a colorful runner rug down the hallway? You can bring interest to the space without it being permanent. Rugsdirect.com has thousands of choices. An alternative (or addition) to that idea is to create a gallery wall down the length of the wall. Hard to tell what is on the wall to the right in the first picture (an electrical panel?), but if you can fit a framed photo over that you have a lot of real estate to do something really fun on that wall. If you do decide on a gallery wall, I'd suggest painting the walls a brighter white. Perhaps they already are, just hard to tell from the photos and maybe it's the flushmount that gives them a yellow appearance. Then I would get frames all in the same color, but varying sizes. Hope you find something that works!

If you want to improve lighting maybe you can get the ok from landlord to replace the light yourself, or you pay someone to do it, a handyman. You would have to leave it if you move out and not expect landlord to reimburse you for it.

Maybe a light with directional lights like this:

this is a very easy fix get a track light with a few heads of a multie head directional light, lowes and home depo sell both for a pretty good price, also amazon and online dealer. it would come with max wattage bulbs so buy a second set of bulbs for it in lower wattage.
