I have petitioned to Airbnb that this guest is a Safety & Security threat, and they are currently looking into it. He is in violation of the site policies by using the review section to lie with the intention of doing me harm, in retaliation for my holding a portion of security deposit for the theft of property and damage to the premises.
Correction: Roy's statement is mistaken. The guest Studio in the front has a private entrance. The host apartment in the back has its own private entrance. There is a locked door separating the two units.
