<human>: Can you succinctly summarize the text in 1-3 sentences?

Recently, my boyfriend and I rented an apartment in Louisville. It is in the old part of the city so obviously it is not brand new, but we've been experiencing way too many problems.

Our air conditioning has not worked since we got here. It is the middle of summer and it is about 80 degrees in the apartment at all times, especially when we cook. They had somebody come in to look at the AC. The filter was not where it was supposed to be. Instead, someone had carved a hole in the bottom of the unit, put a filter over it (CAKED with grime - they hadn't cleaned it in years) and held it down with a SHOE.

The entire time this AC wasn't working properly, we paid for the sky high electric bills it caused, not them.

There are tenants below us who do drugs and party until all hours of the night. Their music is not even just loud - it is at a completely unreasonable volume. It shakes our dishes on the shelves. It keeps my boyfriend's two-year-old up and scares him. We have talked to them AND our landlord about this to no result. Otherwise, we have called the police on them multiple times.

And finally, the BIGGEST issue. There are animals constantly living in the vents in our apartment. First it was a family of raccoons that were constantly crawling through the walls and through the vents, making noises that terrified the two-year-old. They were tearing things up in the wall which was why the man was called to look at our AC to begin with. The apartment's response was to lay out little traps for the raccoons (in spots that were not correct; did not consult us; traps did not work). 

Now there is something living in there that is bigger / meaner. I'm afraid it is rabid or something. A week or so ago we started finding fleas all over the carpet. We couldn't figure out where they came from - now we're thinking the animals in the vent. My boyfriend went to wipe a vent yesterday, and the animal SNARLED at him through the vent and crawled off. It keeps hissing at us from different vents.
<bot>: Air conditioning is a joke, raises our electric we have to pay, animals in the walls and vents, causing fleas - CAN WE GET OUT OF OUR LEASE?
