But two years ago, when I had a three week holiday in Paris
I organized six private lessons (twice a week two hours) at Eurocentres ( http://www.eurocentres.com/ec/en/languages...is-General.html ) a school operated by a swiss foundation. I had the lessons with M. Daniel Moriot the Academic manager. It was quite intense. I was very happy with it.

Thank you Sam for letting me know about Accord.
