I would add: Allow apartments the ability to add at least one other person as a tenant... not just for RP purposes but so others can help decorate said apartments.

And yeah, you're right about apartments not being adequate. I realize that over in JP it's not at all unusual for someone to live in a tiny space and make it work, but this is a little too restrictive and it's hard to 'make it work' when you only have only 100 slots. It can be done... but you gotta get really creative.
