You can decorate your room with flower vases and posters. Hanging wallpapers are also the good one and the most beautiful thing is that you can use small LED light bulbs to give stunning look.
This is the best place to help you redecorate, I used them for my apartment. they are awesome for a person like me who doesn't have the time/patience for redecorating entirely by myself. they do all their work for super low prices too.

You didn't even state if you're a boy or a girl. But you can paint the walls and have posters of your favorite movie (band, popstar, game) on your wall. You can also buy a bouquet of flowers and place it on a vase. Put the vase in the living room- it adds color and life to your place.
