After he confirmed our booking, we were unable to reach Booker. He never sent check in instructions, and calls, messages, and knocks on the door went unanswered. Since we were now in an unfamiliar city with no place to stay, Airbnb had to cancel our booking and put us up somewhere else. His failure to respond caused us a lot of stress and headache, but we were happy with how Airbnb handled the issue.
