He should disclose this information way in advance, which he sent me via text and not AirBnB messages, "...But just have your ID ready in case they stop you (sometimes they do) and just mention you're visiting your friend in apt ***. DON'T MENTION AIRBNB AT ALL. They don’t allow it in my building so I do it under the table. So just make sure if security or anyone else asks, we’re old friends :)"
*** = his apt. number.
I learned this as part of the check-in instructions via text from Robin, the night before check-in. At night, I talked to two AirBnB employees about the situation and saying I was uncomfortable. Next morning at around 12:30am Robin asked why I am not comfortable. I said I would reply on AirBnB messages. After getting no help from AirBnB, I decided to stay with Robin and then he did not want me to stay at his place anymore. AirBnB said he was willing to give half his payout. Ultimately, AirBnB said this is technically not illegal. Horrible experience with both Robin and AirBnB. Actually, I'm scared to post this because no one in the situation was looking out for me. I wasn't even accommodated for the trouble in any way except refund. No discount or reimbursement for time wasted and having to find a place to stay last minute. Be careful and I hope this never happens to you.
