Downtown LA had a bunch of (textile?) factories and warehouses back in the day that got repurposed as residential lofts. They're quirky and somewhat charming big buildings to live in, but you can tell they weren't really meant for humans to live in to begin with. I'm thinking of all of the SB lofts.
For example if you're on the first few floors and you don't have an outside-facing window, your only source of light might be a 20 story light well. At best it always looks like dusk in your apartment, but most often it's pitch black without having your lights always on.
Some of those repurposed building are quite livable, others not as much.
You get used to the constant background sketchiness of it after enough time, but the lack of an easily accessible green space is a bummer. There's Elysian, but it's a decent walk.
