My wife and I spent a week in Julien's unit and it was an all around great experience. Julien was prompt in responding to all messages and was easily accessible for a couple of questions we had. He was also very accommodating in allowing us flexible check-in times due to our flight schedules.
The unit was exactly as described and very clean and neat - plenty of hot water and amenities; we felt like we lived in our own flat in Paris. The wifi was reliable and fast. He cleaned out drawer space and kitchen space for us to use and even had books in English about Paris in the apartment for our reference.
The neighborhood was so convenient and walkable, with a metro stop right around the corner. Lots of great restaurants and shops, some of which Julien recommended and all of which we loved.
I would recommend Julien's place to anyone wanting to feel like they were a resident of the neighborhood!
Thanks Julien!
