I don't think it is a bad deal. Most $150 fixed gear bikes on craigslist are rusty conversions.
Difficult to tell from the photo but that one looks like it might be clean. The saddle, seatpost and stem look original. It looks like a size 53.
I own a 2015 Pista. It is a cromo frame, nothing special, but the steel will be very comfortable to ride. Keep in mind that it has no bottle cage mounts. Replace the bull horns with drop bars and ride it.
Whomever picked the color for the floor in that photo needs to have his head checked.
