Matthieu was very hospitable and his communication was very good. We didnt have any trouble to reach him when need help and have questions.
I should give this information that there is just one seperate room. Bath is inside this room since one wall of the room is glass, it is not very comfortable as it is not sufficiently isolated from other parts of the house. This could be a problem for 3 people. Also flat location is near to metro so it is easy to travel and spent time in Paris.
