That is messed up IF the pictures dont reflect the actual apartment OR if the address is tons of blocks away from the actual location listed. But just so you will know, in all of NY, host can't always put in their actual address due to the very strict LAWS here. Host need to rent out their apartments out of necessity, but they aren't actually "allowed" to do so frequently by their landlords. Host may lose thier whole entire apartment if you say out loud that you are airbnb'ing their place... it can be a mess for the host. It's a New York thing really, and its been this way for many many years (Example: Rent controlled or Rent stabilized apartments - host pay "cheaper" rent, but can NOT sublet their place - sort of unfair, but that's the law).
If I were you, I would call your host and have a telephone converstaion about it. If they really did put you tons of BLOCKS away from the location listed or the rooms don't look like the picture, then cancel - That's not cool!
