I stayed in Chemin Vert 1, along with six of my colleagues, when we were in Paris for an educational event taking place at the Sorbonne. Although I never had the pleasure of meeting Maitis, Jerome, or Laurence (Maitis' sister), Laurence was lovely in messages and quick to respond to any queries we had in advance of our stay. The flat is lovely, well-equipped as mentioned in the description, and a quiet oasis away from the hustle and bustle of the city, despite the fact that it's right in the middle of the 11th. This was truly a great place for a large group to stay!
