I'm sorry, that you felt uncomfortable. Rather, it's been so that since the beginning you didn't answer my messages. You did not respond my greeting, as if I did not exist. But communication is obviously not your strength. And living together and sharing an apartment means communication. As you can see in the comments below, no one had problems with the key. Rather, it is so that I asked about the intercom who is at the door, and you have not responded. Shortly after you have opened without problems the door. And if you entranced I said twice "Hello", and you didn't answer. I'm sorry to say this, but you don't fit into the Airbnb philosophy. I recommend the next time a hotel.
