Learn English – A single word describing a person who is impossible to live with


Is there a single word describing someone who is impossible to live with because of their bad manners?

Such as in the example:

'John, my housemate, has terrible manners; he's an awful person and impossible to live with.'

I thought about using the words 'unlivable person' but that sounds a bit strange to me and it's not a single word.

A person who is hard to put up with may be described as insufferable. A person who lacks graceful behaviour or acceptable/pleasing social skills is uncouth.
