Ask if you can paint?
I'd first ask your landlord about painting the apartment. If you do the work he may agree and pay for all the supplies. A win win. Best of luck.
How about applying fabric, like fabulous sheets, using iiquid starch.... http://www.hgtv.com/design/decorating/design-101/how-to-install-a-fabric-feature-wall or a nature wall tapestry... https://www.twinkledeals.com/wall-tapestry/forest-sunlight-decorative-wall-hanging/p_1077931.html
You could hang a large rug on your wall. Use something like a curtain rod to keep rug straight. You could also use this method to hang a large scarf. Try looking on LetGo or E-Bay to keep cost down.
