Vincent's apartment is very well situated—about 2 minutes of walk from the metro station in a touristy area, so it is safe and quite ideal with restaurants close, a supermarket in the same building, and tourist attractions within walking distance (Montparnasse, Moulin Rouge, ...). The apartment itself is very calm, quiet and very clean. It is relatively small, but it can comfortably host 2 people. I highly recommend it for your next trip to Paris.
