Hi @S193
The listing is new but the Host is a long-time user of the platform and had several excellent reviews as a guest.
Host has the option to offer a New Listing Promo discount which is 20% off their regular nightly rate for the first 3 guests to encourage guests to book. This is a real promo of the platform. Being cautious is natural but bookings confirmed on the platform are protected. You may refer to "Aircover" on your coverage as a guest should the listing be not as expected.
There is a helpful article about that: https://www.airbnb.com/help/article/3218
I hope you find a listing that suits your needs. All the best.
