@Archana18 Really bad idea. There are none of the safeguards on Airbnb that a landlord would normally employ- a real security deposit, references, work and credit history, present employment, criminal record check, etc.
And a guest who stays longer than a month legally becomes a tenant, subject to landlord/tenant laws in your jurisdiction. If they proved objectionable or stopped paying the rent, you would have to go through local regulations to evict them, which could be a lengthy, months-long process.
