You’re welcome! I hope that you continue looking here for information. It will be well worth your time to browse the posts and discussions here, so that you can avoid the perpetual arguments about bed linens and small kitchen appliances and what guests can do to/with them. 
One very important thing about Air is that any kind of internet outage can suddenly leave you without any AirBnB info! We have all learned that it’s extremely important to save all the info for every booking on your PC as soon as the booking occurs. Most of use use a spreadsheet to track bookings, city room tax, and our income. I always copy the phone number there, and put it in my phone too, so I see the name when the phone rings.
And the phone app is limited. Sometimes Air changes software on their web site without making changes in the phone app, and vice versa. We had one incident a few months ago when a large number of bookings were accidentally cancelled, and their phone system was overwhelmed by both guests and hosts. So you need to save guest info offline!
Some here prefer to use the app with tablet or phone, but I only use the phone to check info, rarely to enter it. I have the app on the phone just for Air messaging when I’m away from the house.
And another thing — you want to keep all communication with guests on the Air messaging system, so that if you have a problem with a guest, all the info is in the system where the Air customer disservice person can see it when talking to you. Texting or talking on the phone doesn’t cut it with them.
Enjoy your new adventure!
