Location, location, location.
I mean, the Louvre is across the street! The metro is across the street! The Seine is one block away. Les Halles and Norte Dame and Musee d'Orsay are a couple minutes away. Cafes to the left and right of the front door.
The apartment is perfect for three or four people. It has all the major elements, microwave, dishwasher, water and dryer, coffee maker. It has all the necessary pots and pans, dishes, etc.
The apartment is a grand home base for exploring Paris where a large apartment is not necessary.
Our host, Eric was attentive and helpful.
