There is one aspect of housing that makes apartments a complete deal breaker:

NO GARDENS

What I would like to see as part of the apartments moving forward:

A public area where several members of the apartment have a chunk of yard to do with as they see fit, and enough space to use a deluxe garden or two, so the apartment tenants can garden if they so choose.

This space should be big enough to hold 20-30 (or more) plots of land, and it should also be instanced so as many exist for that apartment complex as needed.
