I also host myself. And unless they do something REALLY bad I would never insult them and ask them to leave my place in the middle of the night. Especially if it is a woman traveling alone.
David kicked me out without any problem at midnight because I complained about the very disorganized check-in.
I don't recommend this host who will cancel, kick you out with no problem because he offers cheap accommodation in a very central area (close to the EU institutions) so he knows he will have someone else right away. Be careful when you book this place.
Also, I am pretty sure I left my watch in his place and they didnt give it back to me.
