Holiday lets and cleaning

I see a lot of these threads over on MN so wonder what a slightly different demographic thinks.

Tales of arriving to find a big book of rules specifying that you have to do X, XX, and XXX that were not mentioned in the original booking rules or notification. People being changed ridiculous fees (eg witholding deposit) for not emptying a bin or stripping a bed in a let where you also pay a "cleaning" fee.

As someone who sells online I am aware of the law (Consumer Protection from Unfair Trading Regulations 2008) which states that for online purchases all terms and conditions must be available for the buyer to peruse (no more than 1 click away online) at the time of purchase of a good or service. This is obviously so that buyers can make an informed decision before paying.

If someone introduced terms I had not had the opportunity to agree to and then witheld my deposit I would be on the phone to my cc provider quick as a flash for a chargeback. I find that just threatening someone with a chargeback gets your card refunded double quick if they are doing a dilly dally.

Have any of you had experiences with witholding of deposits of silly "extra rules" in holiday lets that you were not expecting?

People should not expect to spend the last day of their holiday cleaning up unless this was made crystal clear at the onset and they have agreed to it.
