We had a late flight into Paris and couldn't get to the apartment until 10:30, Charles met us even that late with the keys and showed us how things worked. He speaks English. The apartment is on the 5th floor and there is an elevator. The apartment was very clean, light, quiet and everything worked. It is a 6 minute walk to Place Charles Michel where the Metro station is located as well as a Starbucks, McDonalds, Monoprix (department store and food store) and other restaurants and cafes. It is a 15 minute walk to the Eiffel Tower. By Metro you can be anywhere in Paris in about 20-25 minutes. It is only 11 minutes to Notre Dame. If you need to rent a car there is an Avis location eight minutes walk down the street to the south. You should get a NAVIGO Decouvert card (look online) at the Metro station, it costs 5 Euro and is good for life (bring a passport size photo) and then a calendar week of unlimited rides (Mon-Sun) is only 21 Euro and is good on all Metros, Buses, RER, around Paris and out to Versailles and CDG airport (less than an hour) .
It's a quiet neighborhood and you see parents walking their kids to school in the morning. There are many good restaurants within a ten minute walk and other stores.
Charles is a good guy and I plan to use his apartment again the next time i go to Paris
