How many..

towels do 2 people need for a 2 week holiday?

I look after a villa on our Community, a couple have just vacated it having spent 2 weeks in it.  They have used  6 beach towels, 4 bath and 2 hand towels, both double bedrooms and both bathrooms. It would appear that they never bothered to sweep up or clean the coffee table, I suspect their thought was, we are paying for a cleaner so we might as well make her earn her money.
