I disagree. This layout looks extremely functional to me, especially for a single person, couple or even a small family. Everything you need is there, but no wasted space. Personally, I would love a home with huge floor to ceiling windows to let in the light.
As I mentioned in my edit, the home in the listing actually does have an entrance area so the living room is not visible from the street. I've looked at a few other listings and they all seem to have a similar floorplan, so I don't believe the assailant could see Samantha from the doorway if she was sleeping on the living room sofa.
Here's a walk-through video of another home in the complex. Starting at :32 seconds you can see the entrance area / foyer / dining room as you enter.
