Look carefully at your lease to see if there is any language about guests and if you are liable for guest behavior or damage. Also, some places require that all residents in a unit have to be on the lease and there may be a rule about how many days in a year one guest can stay before they're asked to sign a lease.

As another commenter said, document everything you can. Keep your receipts from your hotel stays.

Even though complaints have been made, prepare to make one in writing and send it by registered mail, and include copies of your receipts.

If you have renters insurance, find out if there's some kind of emergency support for this situation. I doubt it, but asking is always free.

Before going into planning mode, contact the Legal Aid Justice Center for guidance. They'd probably be able to advise you of the best way to proceed.
