I booked very short term, only two days before arriving. Since I got a message saying 'reservation confirmed' I assumed that would be ok. On the morning I was supposed to arrive I got a message from Marvet asking me to cancel my booking as she's on holidays and nobody is there to let me in. I didn't want to pay for cancellation fees so I contacted AirBnB support. They couldn't reach Marvet and so they cancelled the booking for me/her.
