Apartment was a lovely , old, typical Parisian building, with a lovely staircase, which was worth the climbing the five flights for. A bonus was the view of the Eiffel Tower if you were willing to lean out of the window far enough. The mezzanine level was a bit scary and a bit awkward if you are six feet tall.
Everything you needed was there and Boris' bus directions made getting from the Gare du Nord easy.
We would want to stay again if visiting Paris.
