The night before (at 23:26 or 11:26PM) we were to arrive in Paris, Olivier told us that his place would not be available for the first night and instead tried to have us stay with his friend. He was not sure whether his space would be available for our second night's stay and did not have a solution for that, yet, he was resistant in cancelling the reservation.
We were left scrambling at midnight to find another place to stay in Paris while trying to speak with Airbnb support to encourage Olivier to cancel our reservation and refund our money.
This experience was very frustrating and has made me reflect on whether airbnb's service is reliable at all.
