The location of the flat is excellent, being very close to some of the main Parisian attractions (Louvre, Opéra, to name the most important ones) and with a metro stop within walking distance (lines 8 and 9).
The apartment was well heated and was overall cosy; suitable for a family of 4/6 members or even two couples. All in all, a place that makes you feel good and where you would like to return to.
