@Kwame22 Airbnb followed its standard procedure for guests whose bookings were cancelled by the hosts: full refund plus a voucher to apply toward booking another listing on the platform. Usually in a case like this, the host also receives penalties - one of them is an automated message on the listing warning that the host cancelled a booking 0 days before arrival. However, the guest does not get to submit a review when Airbnb treats the circumstances as a host cancellation.
If you had travel insurance to cover your trip, you can check the policy to see if it has a benefit to reimburse you for the extra costs incurred due to being forced to relocate at the last minute. Admittedly, this is pretty rare and not part of a standard policy.
Beyond that, you've probably hit a dead end. Airbnb was obliged to fully refund your stay, but the extra cost of choosing a last-minute hotel and other inconveniences is not guaranteed in the terms of service. The anger and disappointment you feel about having your birthday plans spoiled is certainly justified, but these emotions don't add any enough gravity to your case to be worth any effort to pursue additional compensation. I hope your group still had a good time together despite the crappy Airbnb experience.
