I found a room that looked good to me, emailed the owner asking to reserve the room, and got back from airbnb a form with a very complicated and difficult sign-in process with many steps to it. In the middle of a trip, I wasn't able to complete the application, kept emailing for help, and kept getting form responses which were not helpful.
I eventually had to give up - no more time to spend trying to deal with them. I cancelled my application, but the next day I got an email saying they had already charged my credit card! And this is before they even accepted my application. Unbelievable! They wouldn't complete the reservation for me but still charged me for it.
They did eventually refund the money, but I would never try them again. Traveling with my dog, I now stay in Motel 6. They're not fancy, but clean, dependable, and you can make a reservation on the road with their staff - actual people who are helpful. And they all accept dogs! Takes the stress out of a road trip!
