I booked this for my colleague for a work-related visit. The listing mentioned 1 bedroom so I had no idea it has two bedrooms and that the living room and kitchen are shared. When my colleague reached there, someone opened the door from inside and was not happy to see him. He said "I did not expect you here" and wanted my colleague to leave. I assume the way it was listed had confused the other guest too and he thought that he had the place to himself whereas we thought we booked it all too.
My colleague had a very unpleasant experience of arguing about who is booked and who is not. I rang the host but it was difficult to explain to her and I am still unsure if she understood about the error in listing that created the confusion.
