The location is very convenient because it is near from Gare Montparnasse and Saint-Germain-des-Prés. And we went shopping at neighbor supermarket (Monoprix and Franprix) every day.
The room of the appartment is clean and quiet, and amenity is good enough.
Elena gave us so emphathic support that she answered all of my questions (local shops, etc.) immediately. Therefore this stay in Paris was quite comfortable for us. All of my family were completely satisfied with sightseeing, shopping, enjoying foods, ... and had a very nice time in Paris.
If I have another opportunity to have a vacation in Paris, I will definitely select this apartment again.
