What does apartment with Airbnb commodity mean?

A friend said she rents her own apartment / airbnb. She has her own room & bathroom & living room but the kitchen is shared.

most of the time no one is home but there’s 2 roomates living upstairs in their own room.

im a bit confused and feel shy to ask her. Is this an airbnb she’s renting every day every month and not her apartment? I’m confused. The decor and furniture in the kitchen is not hers.
