The first time I stayed in a holiday let was about 10 years, and I couldn't believe the standard of cleanliness we were expected to leave the house in - I am sure it was so the cleaners could simply glance over and 'check' it, rather than clean.
And no, it wasn't clear in the original T&Cs - just fairly obvious things were mentioned then.
It was near a beach, and of course we had a nice barbecue on the last night and family went for a walk on the beach. They had already booked to leave that night, and we had to leave early the next morning. I had expected to give it a once-over and swipe, but to adhere to the 'rules' we had to get up at 5am to spend an hour:
Stripping all beds and putting laundry in bags
Cleaning all bathrooms and kitchen surfaces and leaving nothing out
Throw away all cloths used, all teatowels to be washed, dried and replaced in drawers.
All rubbish to be put in plastic bags and put in bins.
Cleaning all drawers and cupboards (I'm afraid that I simply gave those the once-over)
Sweeping the yard
Vacuuming the floors and furniture (any sand meant lost deposit)
Of course I don't expect to leave a 'mess' (and I know some folk do) but given the enormous amount we were charged, I expected to leave the place tidy, and 'ready to clean' rather than do the cleaners' job for them!
We rarely stay in such places - actually just once since - and as the family were on tight schedules, DH & I decided to spend the morning of departure cleaning, and go to a hotel for the night to enjoy ourselves!
Actually that was the time we were threatened with losing our deposit as the people who came in complained. Fortunately I had taken photos of the house when we arrived - it was OK but not pristine, and we left it better than we found it. The owner had to go and sort it out, and although she didn't say so, it rather confirmed my view that the 'cleaners' just come in to make up the beds and put out the towels. She apologised and we got our deposit back!
And Redhead56, if I ever say this to anyone, they usually give the same reply as you do! I don't think I'm that slovenly, and as we usually camp, I certainly run a tight ship.
And yes, of course, especially now I am older and less mobile, family would arrange to do the cleaning.
But to me, I don't pay that amount of money (some thousands for a big house) to be the cleaner!
