The flat is in a wonderful location for navigating the major sites and museums of Paris. The Eiffel Tower and Notre Dame are a 15 minute walk in either direction, the D'Orsay, Louvre, Seine and Tuileries are all within a few minutes walk.
All amenities required for a longer stay - groceries, pharmacy, etc., are within a few blocks. Great restaurants and shopping as well. The kitchen and bathroom in the flat are very accommodating, and the large open room is comfortable. A little street noise, but not enough to be a bother. I did not have a need for the loft, other than it made a nice space to tuck away unused items.
As a female traveler, I felt entirely safe. I would stay here again.
