Lysol, and plenty of baking soda. This happened when I was a kid. Lysol, baking soda, and leaving the door open (and the windows open) for about a week. You'll have to unplug it and live out of an ice chest for that time, but this is all we could figure out to do.
If the power going out was due to wiring in the house and you rent, you might MIGHT be able to get compensation from the landlord. If power just went out in the area, then the landlord is off the hook.
