This apartment is very comfortable and clean. There are everything you need, very quiet. The owner is always on-line and ready to help. The location is perfect. Nearest metrostation is 2 min on foot (Raspail and Vavin). Easy access to airports from Denfert-rochereau station (Orly - by bus, CDG - by commuter train). It is close to the train station (Gare Montparnasse), Galeries Lafayette, Museum of the catacombs. The Eiffel tower is a few stops away by direct metro line.
I already know where to stay in Paris next time!
