LOVE those Paris locations!

I recently watched this film for the first time (can't think how I missed it, being an Audrey Hepburn *and* a rom com fan all these years!), and among other things I just love those Paris locations, especially the Bonnet's house and the street scenes! You can tell that it actually was the Paris of the 1960s, and not just Hollywood's idea of of Paris, either. I especially enjoyed the scene where AH and PO are sitting on a bench by a fountain, and you see all the pedestrians passing in the background. Like others, I would love to know more about that house, whether it still exists or was torn down, as another poster speculated. Also, the Kleber-Lafayette Museum sounds like it ought to be a real museum - I actually looked it up in case it really existed!
