The simplest solution is probably a box fan in the patio doorway. Blow the air out or in depending on where you are, the makeup air will be drawn in or out as needed.
A better solution would be to invest in a locking steel screen door for the main entrance, the kind with rigid heavy duty screening material. I'm sure you've seen them around. It screws to the door frame, and usually are dense enough to block casual viewing but are great for airflow.
If yours is a rental ask your landlord about it. They may think it's a great idea and provide it, or buy it if you install, etc.
