@Carly153 If it's a new listing, of course it doesn't have any reviews yet. And you have no reviews as a guest, either. Does that mean you aren't legit? 🙂
This is a listing on the official Airbnb site. There is no reason to think there's anything shady about it. If the host responds to you in a timely fashion and communicates well, you shouldn't have anything to worry about.
It's places that people find on other sites, like Zillow or Craigslist , or whatever, and then the so-called host sends them some lengthy email, directs them to a fake Airbnb look-alike posting, asking for all their ID and then telling them to transfer money where people get scammed.
If you do everything through Airbnb, you'll be fine. Occasionally there's some scammers on the real site, but it's not at all common, and when you pay through Airbnb, they hold your payment until 24 hours after check-in before releasing it to the host, so you're safe in that regard.
P.S. You should add a brief write-up about yourself on your profile. Hosts like to see that and some hosts will decline bookings from a new guest with no reviews who hasn't bothered to fill that part out. Just as guests might be wary about a new listing with no reviews, hosts are wary of new guests with no reviews, so writing something about your work, studies, and interests, can put hosts at ease.
