Catherine was a warm and welcoming host. Be sure to get details on how best to meet her. There was some confusion on our behalf. The apartment was lovely. Clean, all the necessities were available. It was a bit small for a 4 night stay. A very quiet room amidst a busy area. Plenty of places to eat, drink and relax. Markets of several varieties and the metro just one block away. The stairway is wide and seems to be about 2 flights, I think it is advertised as 5? Easily navigable. We enjoyed our stay very much. If we are in Paris again we will definitely request Catherine's apartments!
