Laura: I have a small bouquet of artificial roses.in my vanity area. I put rose oil on a cotton ball and tuck it in the roses... quite nice!
You can add any essential oil to a small container of cotton balls and place them in drawers,etc. I like to wipe them on the vanity bulbs when the bulb is cool. Then the fragrance will warm up and spread when the light is on.
You could simple have a jar of cotton balls and put essential oils on the cotton balls as a room freshener!
