Communicating with Mathieu before, during and after our reservation was fantastic. The arrival and check-in instructions were very clear making the arrival process effortless. The AC units in each room were quiet and very powerful. This was a huge relief as Paris was incredibly hot during our stay.
The location couldn't have been better: next to two Metro stations, half-block away from a Franprix grocery store, close to many great restaurants, and within walking distance to the Eiffel Tour and Invalides.
We encountered just one issue in that the apartment hadn't been cleaned when we arrived. There was apparently a mix up with the cleaning staff and our apartment hadn't been serviced. Mathieu was incredibly apologetic and responsive. He arranged to have the apartment cleaned that afternoon and left us a bottle of wine.
