@Cheryl86 you can follow any policy you like if you clearly mention it to the guests before booking.
I agree with the other hosts that extra linens, towels or whatever else you don't want the guests to use should not be accessible by them. It may not be their bad intention, but sometimes people get confused and they don't get the message so well. So, you can have a locked closet with all that stuff.
My policy is the following:
- linens in bed and one extra set, if you stay more than 6 days
- One set of towels for each guest and one extra set, if you stay more than 4 days
I write that in my listing description and then, in my House Manual. So, it is clear enough.
Now, what would I do if someone asked for more?
If it was something reasonable (f.e. they want just one towel more), I would probably give them for free.
If they asked for a whole set of towels and linens, I would simply say that I don't have more.
If I ever decide to offer more linen, with a charge, I will include that in my description text, so that they are prepared.
