Hi @Carl138,
It’s indeed a bit odd, the host is an Airbnb member for 2 years already.
And he hardly has any verifications (No e-Mail and no telephone number apparently).
He has some unavailability early August though.
Obviously it can happen that a place does not have reviews yet.
When you are not comfortable with such a listing, then just select another listing.
Ps.
A host does not get paid until 24 hours after check-in.
So in case it is a scam, you can always contact Airbnb about this. On the other side: You still would not have a place to stay.
Success!
