The truth is that I was to arrive after 6:30pm for check-in which was agreed upon and pre-arranged. I arrived at just beyond 6:30pm about 6:40pm and spent over 20 minutes ringing the door buzzer and telephoning only to get a "Google voice mail account. I contacted Airbnb only to get someone named Mary who was less than understanding. It was getting dark, I had luggage and was in an unfamiliar neighborhood. I left to take care of myself by finding dinner. By 9pm everything in the neighborhood was shutting down. I had exhausted every possible means of communication and it looked like my host had cancelled my reservation when just after 9pm I left a final message on Airbnb asking if this was some evil trick? That's when my phone rang and it was my host calling to say that she had not cancelled and that I could come over now. It was indeed Mary at Airbnb who cancelled the reservation leaving me with no viable option at this late hour.
I was already at the hosts home well after 9pm when Mary made contact with me again. I finally got a good nights sleep in a charming apartment but was dismayed at the low level of Airbnb customer support.
