Although the neighborhood is not one of the best of Paris, and the building is not the most beautiful, the apt is confortable and has all amenities that you need.
There are 2 subway stations nearby but the must important thing is that there is a bus station 20 meters from the building and the bus 95 take you straight to the opera (where you can take the train to the airport) and Musée d’Orsay where you can go to visit many sites of the city
