Also, @Eleonora87, be aware that the security deposit will only be touched by Airbnb for proven, documented damage and repairs. You cannot use it to penalize guests for breaking house rules. Some hosts state that if a guest smokes in their no-smoking listing, there is a several hundred dollar penalty. But Airbnb will never collect this, so it is not enforceable. A host may hire a company to do a smoke and smell cleanup, and this could lead to a reimbursement from the security deposit, usually less than $100. This is the way the security deposit works. It is hard to get compensation, and leads to frustrations for many hosts.
