Location, location, location. This is the best. Right across the street from the Louvre. Couldn't ask for a better spot. A bit noisy from the street traffic, but not a problem for us. Very clean and new. Roomy enough for the six of us (two adult kids w/significant others, as well as the two of us)
Second floor with no elevator might be an issue for some. Two toilets in closets off the kitchen is a bit odd, but worked fine. Sinks and showers in all 3 bedrooms.
Don't be put off by the musty odor walking through the stairway. Once you're in the apartment there is no notice of this. Well equipped with plenty of linens, dishes, pots etc. Washer/dryer quite handy as well as iron/board.
Eloise is a sweet woman and wanted to make everything as nice as possible. You should really enjoy your stay here.
