|Interesting shot. It's hard to imagine what it must have been like to live in this kitchen and prepare meals there!
Photographically, this shot could do with some boosting. First, the WB is off. Auto WB has picked sunny WB, but indoors, this gives a blue cast to the image. One fix as suggested is to throw away the colours, and go BW (I've done this to rescue some truly horrible colours), but I feel the colours add something to this image, so keep them if you can. You can try adjusting the white balance in PS, but I can never get great results from a simple WB slider, and I prefer to use the colour balance, and adjust the RGB seperately. This image needs some boosting in the reds, and possibly a slight reduction in blues.
The lighting is a little flat, with the windows on both sides being quite low, and no overhead lighting. A little bit of bounce flash on the cieling would help to lift the lighting.
For PP, some simple curves adjustments might help (brightness/contrast/shadow/highlight points), but you can't beat a good dodge/burn for an image like this, and maybe even a little HDR treatment (there's many ways of doing this).
PM me if you would like me to do a sample edit.
