My sister and I arrived in Paris at night (23:00) and weren't able to take the apartment key because it was located in the laundry that was already closed.
I texted my apartment manager at noon, that we will be late and then again in the evening. But he answered nothing.
So, we extra rented a hotel for one night. I supposed, that we could take our key at next morning.
The next morning we went to the laundry where a safe with the key was located and I should entered the code for key obtaining. My apartment manager should have sent me this code, but it didn't happen and there wasn't answer from him... I tried to call him, but the robot answered me in the French language.
Then Airbnb support helped me to refund the full cost of renting and helped me find a new apartment.
But I spent one day of my vacation resolving the problem, my plans were broken, I spent more money than expected and obtained the worst experience.
