My appartment is situated in the middle of Montparnasse, close to Denfert Rochereau, where metro, RER and Orlybus come together, on the ground floor of a classical Parisian 'immeuble'.
A kitchen, living room with couch suitable for accommodating 2 extra people staying overnight, a sleeping room with double bed, a bathroom, together around 40 m2. An excellent way to visit Paris for shorter or longer periods of time, for leisure, study or work.
