I have visited Paris many times over the past 40+ years and have stayed in hotels, rented apartments and exchanged houses. In all, this stay was one of the best in terms of location and accommodation. Clean, comfortable, quiet and safe. And it's on the first floor (not a 4th-6th floor walk-up) and is set on a courtyard well in from the street (near zero street noise). The apartment is roomy (by Paris standards!) and well equipped w/ the essentials. Perfect for 1-2 people/ 3 can manage. Everything works fine--e.g. shower and appliances and the bed was medium-firm just the way I like it. I also liked the duvet/comforter and ample supply of pillows.
The location is as central as possible in terms of attractions and transportation. The RER B to CDG is a short 5-minute walk and is probably the fastest/easiest way to and from the airport. Prime Metro stops are close, too, making it quick and easy to get around town (handy in stormy weather). Marcel met me on time, gave me a complete rundown on the apartment and provided solid tips for eateries and groceries. He's a nice/friendly person and has a good command of English. Very pleased w/ the space, the location and the value. 'looking forward to another visit.
