The apartment was really nice, the location was amazing, two blocks from the metro and the Eiffel Tower, the neighborhood was nice and safe, and the supermarket down the road was a plus, we never got to meet Cathy because we where out all day, but she gave us clear instructions on how to get inside the building.
The apartment was a little smaller than it seams in the pictures, and there was no body soap or shampoo for the shower, and we had a late plane the day that we left and we needed a place to leave our bags for the day, Cathy would not let us leave it in the apartment nor did she try to give us a solution for it.
Aside from that everything was great! A little pricy, but the location was worth it.
