@Andre439 The reviews come from genuine/verified guest accounts which have prior reviews from other hosts. You can be pretty well assured that they're not fake - especially considering that they're not all positive.
The listing is genuine. It has some flaws, to be sure, but it takes a pretty unwise host to accept a request for a party via Airbnb. I don't see the point of requesting a tour when there are already 99 photos on the listing; what you're really doing there is asking the host to take time out of their schedule to do unpaid and unnecessary work.
If you want to be sure your event needs are handled professionally, and that you have an opportunity to tour the location beforehand, Airbnb is the wrong place to be looking. There are many event-rental websites with plenty of locations available throughout New York, which are much better equipped to meet your needs - even if those include overnight accommodation. Why on earth would you rather throw a party in someone else's house in a residential neighborhood? Even if the host promises you the moon, there's nothing he can do to stop his neighbors from getting the party shut down by the cops.
