To put it mildly, those who lived in lesser countries would not find it easy to accept such luxuries is possible for mere students. On the other hand, a lot of high school animes have always loved to exaggerate their schools to the point that they look more high tech and advanced than the White House, so this did not really come as a surprise.

Personally I think the dorm would follow these two priority in order: 1)  boys and girls live in separated dorms, and 2) those who were in a team would be placed in either the same room or next/opposite to each other. That simple.

It's highly unlikely that the Academy would allow different genders to live together, especially given that they are just barely of age. Ruby is practically just thirteen years old, and I'm sure no one would appreciate letting her hear the sound of epic sex moaning across the next door.
