Unfortunately I made a mistake and instead of the 1th floor, I written 41th floor.
Another guest, who arrived the same day, also took all the keys. Luckily we were able to solve this problem after some time. The communication was pretty unhappy. Unfortunately, I could not help much at the moment because we have a self-check-in and I was not in town. The guest is then, because he did not get the door with the right key, just went to another apartment that had not yet passed. But then I had to listen to me that everything was dirty.
The door lock was not broken. I cleaned the apartment in the morning and then closed it.
