I stayed at Antonins place with three teenagers for two nights and it was a good choice in any case. His apartment is modern, chic, comfortable and clean. Also the area around the big and modern Bibliothèque François Mitterand in front of the flad is interesting for relaxing, sitting in cafes or even some shopping. The metro station there (same name) is best to reach in a quick time the main places of Paris.
The communication with Antonin (who was abroad at that time) was very comfortable and friendly. Especially as we couldn't be there at arrival time, because of our very late german train, he arranged everything to get the keys. So we enjoyed our stay very much. I can really recommend his appartement. Bonne chance...
