Excellent experience across the board. I completely agree with the former reviews regarding the quality of this apartment, as well as the wonderful host! This is living vs staying in Paris. St. Dominique is right there with its lovely shops, boulangeries, restaurants ( don't miss Chez Constant), not to mention Rue Cler!
One can wander around nearby Faubourg St Germaine and its' extraordinary hotel 'particulars', or take a advantage of the pedestrian friendly quais. The location and the views are some of the best that I have experienced on my trips to Paris. Kudos to Joss!
