If you are going to Paris for tourism or business trip, Michelle's apartement is definetly one the best places to stay. I had the change to stay there for a couple of weeks in december 2013. The apartment is amazing: clean, modern, nicely furnished and well-located in the heart of Paris, in a calm neighborhood.
I used to go by walk erveyday to Champs-Elysées, for some business meetings. If you are going to Paris, you should stay there. Michelle is a very kind and helpful host , and I hope to come back soon.
