That's probably the whole point - they "just sleep" in their small single occupancy rooms and do most of their socializing in attractive common areas.
If you're wondering how the kids are going to hook up - well, window or not, single-occupancy beats the hell out of literal room-mates, which was my dorm experience. And we sure as hell found a way.
If you ask students whether they'd rather have a windowless private room or a shared room with a window, what do you think the breakdown will be?
