Before purchasing and installing the August smart lock with connect, we had a four digit code lock with Yale. We change the lock with every renter, sometimes daily. That was a major inconvenience. The integration with Airbnb is seamless. As soon as the renter makes a reservation through Airbnb, August send an automatic email to the guest instructing them with set up steps.  We’ve only had one problem with a renter that never set up and is not very tech savvy. I tried walking him through when he came to my house but he even forgot his iPhone password to download the app. That’s where the connect feature came in handy. I was able to easily remotely unlock his door. 
 I highly recommend to any Airbnb host. Just have a back up physical key somewhere in the event that you have a guest like mine. At least that will be far and few between as most people are text savvy these days.
