That is the sad thing, in the City I grew up in, we had a few large "one room" rental buildings were people shared a bathroom that were rather cheap. But those started disappearing in the late 90s. Now, none are left :(
I can still picture one building that had probably 100 rooms. I can see a few men leaning out their window smoking.
That is a shame they are gone, seems no one down on their luck has a way to rebuild their life these days.
