@Laura4624 Your listing appears to be new. You really need to spend some time learning about the difference between Inquiries, Booking Requests, declines, cancellations, and all the rest of the myriad things there are to inform oneself about regarding hosting. There are many articles and tutorials available in the Help section of the main Airbnb site.
Starting off your hosting with a cancellation for which you receive penalties isn't a great way to launch. Read about all the things and if you find any of it confusing, need clarity, or have questions, come here for more advice.
I would also suggest you work on your listing description. "About the space" should be where you describe your rooms, your amenities, etc, not just talk about the golf club. Guests want to read about the space they will be inhabiting. There is also a spelling error- "exiting" instead of "exciting". Check out the listings of other hosts here to get some ideas about how to write a listing description.
