Just moved into a new apartment - how do you stop noise from the other apartment?

Hi everyone!

I just moved into what was originally a one family home that was converted to two apartments. The landlord left the basement door and locked it on both sides. This door however happens to be in the corner of my bedroom.

The upstairs tenant has her living room and kitchen right on the other side of the door. Most of her conversations are clear as day as her voice is quite loud. And when her tv is on I can usually listen along with her. She has great taste in music and the party she was planning sounds like a great time 🤦🏼‍♂️

I have no intentions of asking her to quiet down because she’s in her own home and it would be rude of me to expect her not to live

Any suggestions on how to block sound from escaping through the cracks? I can’t open the door to add weather stripping. I would love to rip the door out and add an insulated wall but I’m not sure my landlord would love that
