We have chose self check-in because we arrived after midnight, 2 am. But the key from the apartment was missing. We had to look for another place to stay. The next day host replayed and kindly refunded around 80% of the payment. Apparently, AirBnB app limits the refund percentage, even if you don't stay at the place.... However, despite the kind refund from the host, we will reduce our Airbnb use in Italy, It is not worth the hassle and financial losses.
