I am a host in Nashville TN. I have hosted over 30 times. All my guests were nice and clean. We love to host. Most of the time, everything has been great. There have been a couple of times, both me and the guest have had problems with the website. The main thing is the guest must be fully vetted which includes a copy of a photo ID. Most recently the mobile was not working properly. When a guest booked, I did not get a notice until the guest called me and an hour and half later I got an email. I hope they have the app working because I rely on the app.
