Hi Jennifer, sorry you are going through this. this is a horrific situation. I had a something similar happen this summer here is how I resolved it.
I had an intern who rented my smallest apartment for 60 days. Before he came, I asked him if he needed midterm cleaning and he refused it.
When I had to go in there for an issue. The important thing I had his permission to enter. Did you have his permission to enter? this is really important. If you do, then you can do what I've done.
I found weeks worth of takeout containers never even moved from the table and dirty drawers in the kitchen. Toilet had not been flushed in days. It was a horrific situation. I took photos of food containers with stuff on them and other things.
I immediately wrote him on Airbnb app and said the toilet situation and leaving takeout containers out in living spaces was a health hazard as I could see bacteria growing on the remnants. He was endangering not only himself but also others in the building as this would attract pests and rodents. Also, the maintenance could not be performed due to the poor condition of the apartment.
I also scheduled the cleaning lady and told him, he had no choice, my cleaning person would be coming and he was going to pay whatever they charged me. If he didn't, I was going to file claims with Airbnb and submit the photos.
I also said if the condition of the apartment prevented the maintenance because the plumber would not go into the bathroom, I would charge him for the damage as well.
He tried to get out of it, but I eventually got the cleaning money out of him.
Here is what I've learned from that experience.
I reduced my long term guest discount and established mandatory midterm cleaning that I pay for. I mention this before they book. They don't have to pay for it, but they will get mandatory cleaning every 2 weeks.
Also, I have a separate sheet for long term guests that they have to sign saying they will take out the trash etc.
But I think you should totally send in a cleaner. Good luck!
