While the details about AirBnB's complete lack of host support is horrifying (even if not surprising because, well, we've all heard another dozen or hundred similar stories), I have a couple of suggestions for the future.
First, get the word "Party" out of your listing title. Yes, I know it's used there as a noun, not a verb, but get it out of there.
Next, in the initial paragraph of your description, modivfy this sentence: "Everything is done to make your stay comfortable and accommodate your needs- whether you are throwing a party or ..." to remove the part about throwing a party.
Both of those bits are just *inviting* trouble. Of the bed-breaking, couch-ripping, vomit-in-the fridge sort.
Lastly, your rates are way too low and probably actually encourage bookings by the wrong sort of guest. I don't care how competitively tight AirBnB rentals might be in your area of Chicago, but $154 for EIGHT people is just way too low. Either reduce your max guests to something like 4, or set a base rate for 4 and then an incremental charge for each add'l guest. The **bleep**ty party-people are looking for cheap places to trash. Charge more and you can anticipate higher-quality guests.
