Thanks to Sylvie for her advance instructions and recommendations. Her place is small but charming (under the roofs of Paris - think wood beams on the ceiling) and well appointed. The neighborhood is busy with life and walking distance from many monuments and landmarks. The Cafés are full and there are plenty to choose from if you want to go grocery shopping.
Just a word of caution - No elevator and so the 5 flights up do mean something but by the end of our stay, we were almost used to them (!).
Have a great time in Paris. The city remains magnificent.
