I agree, if they wanna have apartments to be a decent alternative to Housing, the least they could to do is not make it smaller than a house and restrict player freedom and creativity, like you said I wouldn't mind it being an upgradeable feature which would yet another gil sink into the game for those that want it and makes it something to work towards as well. RNGues hates me, so I'll doubt I'll ever win the lottery not that I won't keep trying but the ONLY advantage Housing should have compared to Apartments is an outdoor feature, even then, one could argue about opening up gardening to be more of an indoor thing as well but that's a whole other story.
