I used to walk over to see it regularly when I worked nearby, but now that I don't, I haven't had that pleasure. However, today and tomorrow (and yesterday), the building will be open to the public. It will then close again, for reasons that aren't entirely clear to me, but probably to finalize a few last things before it opens for good to the public. I'm stoked and am going to head down there today.
Until then, please read this nice WaPo article about the building and restoration:
ETA: And here are some pictures for you all:

are open/exposed. This would've been a second-floor fireplace.
