Dirty Beach Grounds for a Bad Airbnb Review?

I am new to the Airbnb life. In August 2017, I rented an ocean front beach house for the weekend in Westbrook, Connecticut. I gave a surprise gathering for my boyfriend’s 46th birthday. The home was beautiful, a little outdated but nice. I met with the maid upon arrival and did a walkaround. The event was very adult and respectful to the home. The area of the beach that the host was responsible for was filthy though. We did not get to enjoy it because it had sea weed, dead crabs, sea shells open and closed, and black dirty sand everywhere. We dared not take off our shoes let alone spend very much quality time out there. A bit depressing being that it’s listed as an ocean front beach home.

However, I gave a guest review. I was mild about the beach. I did in fact mention that it was a disappointment. I didn’t give the details as I just did. The host must have gotten upset and posted a untruthful guest review, saying that my guests and I didn’t clean up behind ourselves, which was an outrage. I have pictures and video footage of the home right before we were checking out. I’ve been trying to send this information to Airbnb but they are giving me email addresses that are coming back to me not received. I need to prove my innocence. Since then I’ve tried to book two other places and got denied because of her lying statement. I need this removed from my review page and this is why I’m fighting.
