Repair dripping faucets. Keep fresh towels in the bathrooms. Use special cleaning products to remove stains from toilets, bathtubs, sinks and showers. If sink and bathtub drain slowly, unclog them. Have all plaster in top shape.
Check ceilings for leak stains.
Fix the cause of the damage, repair the ceiling, and paint. Faded curtains or bedspreads can be dyed bright colors. If you have a fireplace, clean it out and lay some logs in it to make it look inviting. Replace broken glass. Mend torn screens.
