Caterina's Apt. is great. It's comfortable, modern and in a terrific location in the 18th. The bedroom has a nice view of Sacre-Coeur (and the Cimetiere Saint-Vincent) and it's only about a block from the Metro. It is more spacious than the typical 30 sq. m. apt. and we enjoyed the the modern Kithchen and Bathroom. I especially appreciated Caterina and Milena working with us on a flexible check-in as we were being driven into Paris by friends without an exact arrival time. They were great about making it work for us.
