I only have 1 week left available in summer and I got a request for these dates by a company who wanted to open a shop in my house for 1 week, obviously this is not the purpose of my listing and I really dont think its allowed. How can I cancel the dates without being penalized?
Call AirBnB and have them cancel the reservation on their end. I am sure your home is not liscenced to house a business and Airbnb cannot force you to violate zoning laws.
