Daphne's place was wonderful. Very close to a Metro Station (just around the corner), very close to a bus stop (bus 82 from Eiffel Tower stops just across the street!!), and in comfortable walking distance to Gare Montparnasse (think train to Versailles and Le Bus Direct to and from CDG airport). We had a nice walk to Luxembourg Garden which leads to Pantheon and Notre Dame. A very good base to explore Paris!!
Don't forget the nearby cafes and creperies for some late afternoon wine and food. Simple and clean place with shared bathroom and living area. The hosts, Daphne and Martin were very easy to contact and very helpful.
Would definitely recommend to whoever is considering this place.
