Hey, what about coffin motels and the other possible options with a squatter lifestyle, like, say, renting a garage space? I find both of those to be quite interesting alternatives (which might even work!) Compared to the hobo-lifestyle. If you don't have any possessions other than what you can fit in a bag, a coffin motel is actually a viable lifestyle for you. Even if you have a bit more gear but you sleep with it, there shouldn't be much problem (as long as the cubes aren't, you know, actively in use by others or have actual manned staff who might get upset at you sleeping with your AK-97.
But when thinking of other possibilities such as the garage, it has it's own perks, too. First off, it has a door with a lock (and the player can be encouraged to buy a better one by himself), and lots of storage space. I'd be aghast if in God's year 207X you couldn't manage to cook food, sleep and maybe have a bio-toilet in that place. A shower might be harder, though I could see it happening, provided there'd be a drain in the room... Mainly why this would be a squatter instead of a low lifestyle would be that it isn't an apartment, it's a single room. And even if the player CAN live there, it's a hassle and he shouldn't. For example by saying that he needs to shower and bath somewhere...
And after all this I present to you: The GarageCube lifestly (1000 nuyen a month). You rent yourself a garage for holding your gear, privacy and the ability to cook food with your portable cooker and a Cube from a coffin motel nearby, allowing you to stay sanitary, use a toilet and sleep there too, if you want!
...And we shouldn't forget Cyberpunk 2020's "life is disposable" attitude either.
