Litter box help?

I (26M - US) want to adopt a senior cat soon, but the only thing holding me back is the litter box odor. To me, even clean litter boxes have a smell to them. I live in a one bedroom apartment, so are there any things I can do to mitigate that? Growing up I always had cats, but we had a larger house to put the litter boxes in other rooms. I just don’t want the scent to surround my apartment! My goal is to give senior cats a retirement home with me :)

Thanks!!
