Well hello @Kathryn777
What makes you think it's a fake? It has great and recent reviews, it's been verified by Airbnb.
It's always a good idea to send a nice message to a host to introduce yourself and tell them a little of your plans and ask them any questions by using the "Contact host" available. This is an enquiry and the host has 24 hours to reply to you and your credit card is not debited. The way they reply should allay any fears you might have and then you can book if you are happy.
All the best
Joëlle
