Location! Location! I've been to Paris many times, but Mary's and Regis' place is located in the best possible place, street, neighborhood. Walking distance to most spots, quiet street, lovely rooftop view. (Beware - the 100, windy steps to the entrance take time, even for a person in shape. And there are more steps once one enters the apartment). All worth the trouble, though. We had some trouble entering the apt, as the hosts were out of town, and another agency was given the responsibility of helping us. They were not given the street door's access code to enter nor the wifi code, location to the TV remote. All of this was solved within the second day of our arrival.
