I booked a long-term stay for a two-bedroom apartment in NYC on Airbnb for two people. When I was doing the search, it showed the same price for one, two, or more guests in the same apartment. The confirmation came back for one person somehow, so I immediately (less than ten minutes from booking) corrected that in the app and received another confirmation for two people.
I was looking into the address details of the booking I just paid $3,500 for. Surprisingly it still only showed the street name without any other details. So I contacted the host — appeared to be some company instead of an individual host — who insisted that because the reservation showed only one person (who is rich enough to book a two-bedroom apartment for just one person in NYC?), they wanted to charge me more than $1,000 for it.
I looked back into the app, which in fact, still showed the same price for even three or four people. They claimed that it was a system error. At that point, I believed them, and allowed them to cancel so I could rebook. There were plenty other properties around that did not cost more than what they originally charged plus $1,000. This was within 20 minutes of booking.
I contacted Airbnb support. They said that on their end I was confirmed for two people and the price was right. So I let them handle it. The operator also said if I felt uncomfortable with the host, I could cancel for free within 48 hours. The next day, Airbnb support called me, informed me that the host insisted on extra charges even though it was advertised with two people with the price I already paid. And if I cancelled, they could only offer a $150 coupon to book again on Airbnb. They just pocketed $3250 dollars.
The host claimed it was an error with Airbnb, but they refused to accept the full refund cancellation request. Instead they intend to just keep my money or ask for even more. This is all within 24 hours of booking. So, Airbnb leaves me with two choices: either pay $1,000 above the market rate to accept the booking, or lose $3,000 more to cancel. That is the place where Airbnb want their customers to be.
Since you had a reservation confirmed for two you had the legal right to show up, if you had done that they would have been forced to
either accept you or cancel your booking, and doing the latter would give you the full refund automatically. Hopefully, this information helps you going forward.
99% of the Airbnb units in NYC are illegal. If you have the street address report them

Airbnb is all about the bait and switch. Fight them.
