I had a situation like this when my landlord was just such an irresponsible pig that he just didn’t even clean the apartment before I moved in. I was supposed to move in a clean place and I came in and there was grease and grime everywhere. I was shocked and actually wanted to cancel the lease then and there, but it was a great place location-wise and I had no idea where I would find something similar.
I ended up calling a professional cleaning crew that cleaned the place for me. I googled End of Tenancy Cleaning Near Me and honestly called probably the second company on the list. I was actually pleasantly surprised with the way they worked since they cleaned everything fast and efficient and it didn’t cost me as much as I feared. I still sued my landlord for it and he payed me back but I am still glad I found out about them. Anyways I hope you managed to resolve all your problems
