This is a valid argument, which leads me to the thought that the laws need to be updated. I personally wouldn't be okay with my own premise. I have a person coming over to clean, but I am always home and I can check if I am worried about something.

If that's not too intrusive a question, I would be curious to know about your fears regarding such situation? Many people would consider this a benign thing - after all residential cleaning services is a multi-dozen billion market worldwide, growing at 5+% YoY, and a non-trivial part of that necessarily involves letting cleaners clean without owners' supervision.

Then again I'm asking as a European citizen living in a country with a comprehensive legal system, a functioning police force, cheap insurance policies, so on so forth. Certainly that ecosystem plays a role in our inner fears.
