We stayed 3 persons in Didier's apartment from 16th to 23rd October. It is a very nice apartment with good rooms, toilet and bathroom. Nice view from the French balconies to the small street, which was a quiet street during the nights. We felt the area/street were very quite and safe to walk through - also during the evening.
Two Metro stations in a distance of 300 - 450 m. A lot of busses were also available.
We bought a Traval Card from ile de France, called "Navigo découverte" , which covered all buses, Metro and Regional train. We bought it at the train station in the Airport. The price was only 22 Euro for a week card from Monday to Sunday. Can be recommended!
Didier took good care of our arrival, even we were 4 hours delayed with the flight. We get good information when we arrived.
We can recommend the apartment.
