The host has many listings within the same building. Before checking in they could not let us know our specific room.
Only during check-in we were assigned a room and received our keys.
Unfortunately, after an hour of arriving, another group walked in to our room. There was a clear double booking. They had booked another listing with this host. At check-in they were assigned the same room and given same keys.
This is inexcusable and a mistake that should have been avoided.
Both our groups were very frustrated with this host and we felt incredibly unsafe that this happened.
This added undue trouble for our holiday plans.
However, we were all able to contact Airbnb support and Airbnb intervened quickly. After their involvement, Airbnb offered an alternative safe and reliable accommodation for the remainder of our stay during the holidays.
