I was searching for a Paris apartment for 2 with local flair, yet high-quality. This was exactly what we were looking for. The apartment is professionally run with luxury hotel linen and amenities, new bathroom/shower, yet still has a homely feel with the church decorations. It has just about everything you would need and no more (the TV experience was funny). The bedroom is extremely quiet - despite street cleaning every morning - and the bed really comfortable. We loved the view to Notre Dame and the middle-age narrow street below.
For transport from CDG airport, just take one train (B / yellow) and get off at St Michel-Notre Dame. From there it is a 5-8 minute walk. We used this station for all our needs around town when we did not walk - metro, train, etc.
The elevator is cute, but more of a hassle than taking the stairs - just use it for bags (if they fit). :)
Michel was our contact person, and he was really responsive - within one hour.
I can recommend the creperie just a few steps down the street - nice people and good food.
All in all an experience that truly enhanced our stay in and impression of Paris. We felt like locals for a few days. :)
