@Brook19 Firstly, I'm sorry that this has happened to you. I would point out to Airbnb that the guest left an excellent review and it seems he manufactured some complaint to Airbnb after he read your review of him to get even.
Yes, Airbnb considers hosts guilty until proven innocent. You would think their operation is based out of some country with a dictorship as the govt. rather than a democracy.
As Colleen pointed out, there are better ways to write a review. For one thing, never say anything deragatory about Airbnb in a review. That comment was unnecessary and may be why they suspended you rather than the guest filing a complaint.
As a fellow host I don't need to know that the guest ordered a package sent, that they left a surprise under the pillow. I need to know "Guests were disrespectful, house rules were ignored, a mess was left in their wake. Not recommended."
If you are angry about the guests, don't rush to leave a review. You have 14 days- wait until you've calmed down to compose a brief, non-emotional, professional review. And try not to take everything personally- many guests who leave a mess behind them aren't really showing disrespect to you- they are just slobs and they probably live like that at home, as well.
And I realize that the condoms were just the icing on the cake with this booking, but if you are going to host, this sort of thing is not unusual and something you need to get used to and accept as part and parcel of accepting paying guests to your home. I can assure you hotel maids deal with this all the time. And mentioning personal things like bodily fluids, used condoms or female sanitary products, in a review is not considered to be okay. That is all covered under phrases like "disrespect" or "extra cleaning required)
