The location of the place is awesome. If u are anyhow out and exploring Paris, this is great. The communication for us was very difficult, as Mathilde only speaks french. Also it seems like there is a pool of standard answers that you will be sent when asking a question. Our question on where to put the keys when leaving was answered with sth not even related to the question.
Also, be aware that there are no windows that you can open in the appartment. The only outside air you get comes from the door.
