an awful situation to be in
Hopefully you accepted this booking as an Airbnb at Work booking - as third party bookings are not covered by Airbnb - which means Airbnb don't need to cover any damage under their guarantee. @Sal-and-Rob0
In your situation I would have asked Airbnb to cancel the booking straight away as two people are staying not the one booked and they have three dogs staying against your pet policy.
Tell them you went to the premises after complaints from neighbours about dog noise and that the guest didn't respond to messages regarding this .
say you were knocking at the premises for twenty minutes without response and that eventually a female visitor not on the booking let you in and there was clear evidence of three dogs at the premises and dog mess and urine smells everywhere. And that they had blocked off access for a commercial tenant occupying a separate part of the property .
presumably you took photo/video evidence ?
what did the female visitor say when you told her that she and the pets needed to leave as they were not on the booking?
And who is the commercial cleaner you mention and how did they access the property?
your issue may be that it's against Airbnb T&C to enter the premises while a guest is in residence so be careful that Airbnb don't suspend your listing because of safety complaints by the guest.
