That seems like an important distinction, and makes the rest of the article (which focuses on educational accommodations) look mistaken.
This is not entirely their fault. Stanford is subject to Santa Clara County building regulations, and those tend not to be friendly to large university developments (or any large developments for that matter).
I vaguely recall the recent Escondido Graduate Village Residences (EVGR) construction taking a while to get through the regulatory pipeline.
The true underlying issue here is just that there is not enough quality housing for the number of students Stanford admits.
The people in the twins were not happy - they hadn't asked for them.
I knew one person who dropped out in the first 3 months (for mental purposes), and that was someone who shared a room.
The point is that everyone who gets a single is super happy about it the same way that a drug addict is always happy when they get their drug of choice for free: of course it’s great. Of course it isn’t the best thing for you in the long run. I say this as someone who hated being in a double my first year and spent the next three in a single.
As far as I am concerned having apartments of 4-8 students where each has their own small room but shares a common space is ideal. But usually this is reserved for sophomore year and later.
Maybe its fine for many extroverts, but forcing an introvert into a room with others is a great way to drive many people absolutely mental.
