When I arrived in San Diego on a PM flight I got to the Airbnb and found the lockbox code didn’t work. I texted the host and he called right back. He told me that the unit had been double booked and that Airbnb was supposed to get in contact with me and he was really sorry and that I should contact Airbnb. I don’t know who is at fault here, Airbnb or the host, but arriving in a place you don’t know at night and finding out you don’t have a place to stay at 9pm sucks. Dealing with the Airbnb customer service also sucks. I was ultimately given a full refund for my stay but not much else. Lessons learned here: get a personalized confirmation from the host! Don’t just assume you have the place just because you got an auto confirmation along with the charge to your card (I know, typing that out seems crazy).
