Marie-Helene's place is fantastic. It is in a great area with 4-5 cafe's down the street towards a square. In the other direction there are some quality restaurants. If you prefer to cook your own food there are two stores within a two minute walk and a kitchen to use. As for traveling the city there are two metro stops each on a separate line within 5 minutes walk. At night there is a good view of the Paris cityscape with the Eiffel Tower. The apartment itself is wonderful so if you're looking for a place for a few days in Paris you can't do better for the price.
