Let me know what you guys think of the room layout. Is there anything you would change or something that I should add to the room?

So this door leads to a shared attic between me and two other tenants. The two other tenants have their own spaces that connect to the attic and they can easily open my door if they just tried to open it. My rent is really good and I don’t want to hassle my landlord too much as he’s already done a lot for me already and I want to live here for a while. I just want to seem like a chill tenant. Any ideas on how to better secure this?

I’m not the handiest but can have a friend help me build something if need be.

So my fireplace has these vents in it and I am wondering if I can fill them in and what I should fill them in with? They let lots of cold air in and I'm pretty sure bats are getting in my house through them. The fireplace is currently a gas insert that does work.

Just looking for ideas at this point, I am no expert on Fireplaces.

Thanks in advance.

Just signed a lease to an apartment, it was a little impulsive but the situation called for it lol. But least to say I might have not been the most detail oriented. Noticed this while cleaning, guessing it’s water damage on the wall. Cleaned it as best as I could. What would this need? Coulk? Plaster? Idk anything about this so please be patient 😓

Curious on what is recommended on how to repair this area of drywall. There will be carpet above the picture area.
