I'll probably get attacked for this, but here goes . . .

Have recently taken on some (supposedly) swish apartments locally for a London company who are leasing them for 6 months or so.
It's a basic weekly clean of 16 flats, toilets, kitchens, etc.
We've got into the final one of the 16 and, boy, is it a complete and utter mess.
There's food on the floor, empty fAg packs, sweet wrappers, plates, clothes, condom wrappers, etc, etc .. .. strewn all over the place.
Ironically, it was the only place we couldn't get into first to check . ...
My girls have said that if it's like this on a weekly basis, they want no part of it. Now, these are experienced ladies who have seen student digs in a better condition.
I've emailed our contact and have been full and frank ... .
Any suggestions on how to take this forward?
It's 2 (supposedly professional) guys sharing this place. It may just be a culmination of months of neglect, but I don't want this impacting our otherwise great relationship with the customer.
