@Judith630 It sounds to me like this guy simply had no concept of what an Airbnb is, if he expected you to act like his personal maid.
As for his walking around partially clad, he probably just doesn't think it's a big deal. Personally, neither do I, but of course you have another guest to consider.
I live in the tropics- the weather is warm- it doesn't bother me at all for a male guest to go shirtless and boxer shorts are little different from men's surf shorts, even though one is considered to be underwear. Nor would it bother me for them to be wrapped in a towel after a shower.
And my female guests will often just be wrapped in a sarong.
As for the stove burner left on, that's in another category- it's a failure of attention and a fire hazard.
