<p>The doubles are comprised of two rooms, but only the “outer” room will have access to the hallway, so the person living in the inner room has to walk through the outer room to get out. There’s a door and a whole lot of wall separating the inner room and outer room. It’s been a while (3+ years) so I can’t remember if that door can be locked – I think it can be from the inside? – and I’m not sure which direction it swings … I don’t recall having issues with it though, and if your son makes it clear that he doesn’t want to be disturbed when the door is closed, there shouldn’t be any problems.</p>
<p>Inner rooms tend to be bigger in terms of floor space. I think there’s less closet space though. Both will have similar views from the windows as long as the window’s not staring into a tree.</p>
<p>They don’t assign which person gets which room, so if you value your privacy, I highly suggest you get there pretty damn early during move-in day to grab the inner room. 
Otherwise, you’ll have to set up some rules with your roommate.</p>
