Hello @Dev4
I'm surprised you haven't had this conversation with this guest before.
Why haven't you spoken to him about your expectations around how communal areas should be kept and pointed out to him in what ways he has broken house rules?
It's not a good idea to be managing your listings in such a way that you have two guests leaving because another isn't keeping to your house rules.
How often do you/the host go into keep the communal areas clean at the listing?
In answer to your question, I would just be honest and say that this won't work for you as other guests have expressed concerns about how he maintains communal areas. (this is made more difficult as it appears you haven't spoken to him about these issues in the month plus he has stayed).
