This was my worst Airbnb experience. Quite traumatising. Stupidly, I had booked 2 nights, but I thought I had booked 3 nights. Simple mistake. I got home on the evening of the 3rd night, saw the cleaner, who welcomed me into the property. My bags had been packed, which was odd, but I didn't think more of it.
I stayed at the property for 1 more hour, before going out for dinner. When I came back 2 hours later, someone had been in the apartment and had taken my passport.
Once I checked the messages in Airbnb's app, it was apparent that the property managers had done so, and were now expecting 120 GBP before they would have my passport returned.
I'd definitely made a mistake and was willing to pay for it - but this part feels like theft/extortion. Maybe I'm wrong, but you decide whether you want to take the chance of being treated like this.
Then, to make things worse, I was not allowed to extend my stay (despite no-one checking in that evening) and was out on the street at 9:30pm trying to find a hotel that had room (which there were none of).
Again. Up to you. Just know to hide your valuables/passport and there's no room for error, or you're out on the street.
