The apartment is very clean and located in a quiet, safe part of the 14th arrondissement. The particular decor is not for everyone, very much a matter of taste and hard to avoid since it's everywhere including the bathroom. The bed was very comfortable. Having a supermarket right downstairs almost next door is super convenient, as are the 2 metro stops in within walking distance. The Fondation Cartier with its amazing building and the Montparnasse cemetery are both nearby, which is nice for culture-lovers.
There aren't too many food options in the immediate vicinity but it's an easy walk to Rue Daguerre and all its restaurants and shops. I'd say the only unpleasant aspect of my stay was that the door from the hallway to the apartment can sometimes be hard and time-consuming to lock behind oneself (owner acknowledged this problem, calling the door 'a little rebellious'). Otherwise I recommend.
