Hosts were incredibly rude upon entrance. I was threatened that I would be kicked out if I did not pay an additional $50 for an upgrade per their guidelines. I had provided my ID with non-Chicago residence listed. Upon checking their guidelines, I found out that the Chicago policy did not apply to me. I told the staff to provide a refund and concerns about trust / safety of the management team. I was repeatedly told that I was unwelcome to the room that I had signed up for. Within the room, the bathroom was a complete mess and was unsanitary. Upon leaving, I was met with an incredibly rude front desk manager. I voiced my complaints again and requested that they create a more honest and transparent listing on AirBnb. I was met with rude and racially insensitive statements and gestures by the host. Upon telling the staff that I would be reporting them and requesting a refund through AirBnB, I was falsely accused of threatening the staff and told that they would unrightfully respond in kind. Many false allegations were made against me in a threatening way to make it appear as if I had been in the wrong - no acknowledgement was made of the fact that I was unrightfully overcharged, of the poor host experience provided, or of the unsanitary nature of the room. I had expressed safety concerns in the chat the night before, which were not addressed at all. The location has a very well-thought out and planned course of action to ensure that the illegitimate over-charging process is defensible at every step.
