What's one thing I can get/do to make my first "adult" apartment a bit nicer?

Move in is the next few weeks. I've lived on my "own" (roommate I never interacted with) for a couple months my last semester of college, but that was a temporary setup whereas I'm hopefully moving out for good this time.

Bear in mind that the place has window/wall A/C and electric heating.

Things I'm already considering:

• Drain guard
• Bidet
• Cold brew coffee maker
• Rice cooker
• Space heater? I'd like to keep the temp largely down during the winter to save money while warming up the part of the place I'm in
• Key for washer/dryer

Things I already have:

• Most furniture
• Air fryer
• Seltzer water thingy
• Meal prep containers

General advice is also welcome!
