Oooh that sounds a bit nightmarish.
When we last moved the owner wouldn't let us in in the morning to clean (though the house was empty anyway ). We arrived in the afternoon, with deliver people and we then had this army of cleaners in the house till 8pm, as we'd paid them to do a mega clean (it was filthy).
At about 4pm, our childminder unexpectedly turned up on the doorstep, with DS, who had diarreah!!! (sp?)
We couldn't get into the toilets because there were cleaners in there - ditto all sinks with running water.
So DS sat on a potty in the hall (aged 4!!!) in the freezing cold, pooing for England, while I tried to clean him up with baby wipes. It was Febuary, so really cold as well.
Seems funny when I look back, but wasn't funny at the time.
