This is a great apartment in a very central location. Everything was explained to us by Mathilde who was very nice. Instructions for the stove and appliances and equipment were clean and accurate. The towels were nice and warm on the towel racks. There was a bottle of champagne in the fridge. They offer a full concierge service, but we didn't know that before we got there and had already arranged for multiple outings (try WithLocals; it's a great way to meet local folk in Paris, and you can choose from various guides who can tailor and personalize anything you want. We wanted to meet local artists, and Isabel, our guide, was able to take us to one artist's house for dinner where we saw his studio and art and met several of his friends for a delicious homemade meal and to another artitst's house/studio where we were served lunch and surprised by an impromptu jam session and singing).
If you look out the big front windows of this modern apartment, you can see the new large shopping mall off in the distance (not our thing, but right by there are some impressive streets with restaurants and cheesemongers and the stuff you go to Paris for--though a little more touristy than the Marais where we stayed the last time we were in Paris). There's a Metro station about a minute's walk from the front door and a grocery story across the street and an ATM right outside the door, and Uber had no problem getting to us within a few minutes. Mathilde offered to set up a driver to pick us up from the airport and take us back to the airport. It was 90 euros each way, a little high, but it was nice just having it in place and not having to worry about it and having an English speaking driver meet us in the terminal. The apartment is on the 2nd floor, but there is an elevator if you need it. From the apartment's many windows, you can watch (and hear) the hustle and bustle of Paris outside, many people scurrying to and fro carrying on with their daily lives. So it can be noisy, but that's part of the charm of Paris and not unexpected if you want to be located centrally.
