I rented out a room in my apartment I rent on Airbnb over 14 days. Where can I put my expenses of a part of my rent and utilities?

The apartment I rent is not my own. And I have expenses that I need to list against this income. Can I deduct my expenses? And if so,  where can I deduct  part of my rent and/or utilities for the percentage of the room that I rent as compared to the size of my apartment?
