I am sorry to be rather late with the reply. Below should not be taken as the complete piece of processing but rather as a direction. I do all my processing of this kind in PhotoScape which is a nice little tool if one has to try something quick. What I've done was like this:
1. Went sepia.
2. Cropped the bright offending lamp on the top.
3. Played with curves, brightness, contrast.
4. Partially desaturated so that sepia won't be too strong.
5. Applied a bit of vignetting in top right and bottom left corners so as to take care of yet another bright and offending lamp.
6. Played some more with brightness and contrast.
7. Resized, added a frame, saved... Done
Here is what came out:
