How to get correct perspective?

Hey. Im trying to model a room after this Windows 10 image.
This is my first time doing anything else than abstract in blender, so im using this as a reference image to get things right, however i have a few problems.

I’m struggling to get the perspective correct. No matter how i change the position of the camera, and the focal length, something is wrong. how can i fix this?
(this is as close as i get, and if you look on the bottom and top of the walls, there is something wrong. http://i.imgur.com/pvazkPs.gif)

I have also tried setting it to fisheye, with no help.

move the camera to the right.

Wow… Just wow…
Well, thanks, but i’m a bit embarrased that i didn’t figure that out myself…
