Bastien saved me from someone else who cancelled less than 12 hours before my arrival in Paris.
His place just big enough for one (or two who live each other very much). It’s well organized, practical and served my purposes well. His girlfriend arranged key handover, Bastien was always available, it was great communicating with him.
The only minor note is that the apt’s two windows open toward a courtyard with a veeeery high wall of the adjacent building. There is no sunlight, ever. However, since we had to work, for me that was a minor thing.
