Looking after a holiday house, what do I do about laundry?

Hi I am cleaning a holiday house for a friend. There is a two week booking coming up soon, as there are no laundry facilities at the house, what would holiday makers expect regarding bedding/towels. This is my friend's first booking so we aren't quite sure! Should we offer that after a week I would bring their bedding/towels to my house and launder, or do we leave spare bedding/towels, enough to last two weeks. What does anyone think? Thanks
