I own a house in Spain which is let. I wanted to visit my house to inspect and looked for a local property to stay for a weekend. Wasn't I lucky to find my house was available on AirBnb. I contacted Air Bnb who said that they would not take the posting down until instructed by the tenant. I cannot contact anyone at AirBnb and even though my tenant has left my house remains on AirBnb. I hope that when you rent a property as I have done regularly on AirBnb you have insurance and that the property meets local letting regulations. i do hope AirBnb read this and actually remove my property before I become liable and as such I hold AirBnb liable.
Your post triggered a question about tenants listing a property that is not their own. Even though most rental agreements include some language about whether sub-leasing is allowed or not, I am not sure how this can be enforced especially in another country.
I wondered what, if any, safeguards Air BNB would have about propertery owner's permission to sublease.
