@Tom80, @Karin38,
If you are talking about the professional photo services paid for by Airbnb, those pictures are their property. Says so right on the Photography page:
If you choose to use the Airbnb photography service, you recognize that Airbnb will hold all rights (including copyright rights), title and interest in the resulting images. Airbnb may use the resulting images for advertising, marketing, commercial and other purposes in any media or platform, whether in relation to your listing or otherwise.

Of course, you can do anything until you get caught.
