I was met with blatant hostility and lack of respect as when I called the host for clarification on a technical question about their check-in system.
Something like:
"Hey! I have a question about check-in here."
"How can you possibly have a question? It's all written in the documents sent to you."
"I read it and there is one thing I was unsure about."
"Then you obviously haven't read it closely enough. Read it again."
And so on.
They monitored us with cameras and added two people to our booking because some entered the flat to help carry our bags inside
