@Odette67 Airbnb automatically blocks bookings that fit certain criteria that are deemed to be a high risk for parties. The host can't disable that block. You can try having someone else in your group do the booking, especially if you happen to be under 25.
@Bob297is probably correct. You have no reviews. A New Guest trying to book for New Year is a red flag an a possible recipe for disaster/party/trashing.
Not that I am suggesting that this is your intention, but to be honest, Hosts put up their private homes and take risks when hosting and need to protect their investment.
@Odette67 If I were you, as a new user with no reviews, I would fill out the profile write-up section. Say a bit about yourself, your work, your interests, so hosts get some idea who they are deling with. Asking to stay in someone's private home isn't like an anonymous hotel booking.
