Cathy's apartment is ideally located to the centre of Paris, with the Eiffel Tower just a short-ish walk away. I stayed there with my parents so it was a little squeezy, but this wasn't a problem as we spent most of each day out and about and were only really in the apartment to sleep. The beds were comfy and the apartment was warm (in winter) even before turning the heating on. The metro is close by, as is a grocery store. We were there for four nights and enjoyed every minute.
