The communication with Antoine was quick and easy. We had no problems at all. The apartment is located very close to a metro station so you can get everywhere quickly. The neighborhood is also nice with several opportunities to eat and buy groceries. We could use the kitchen and the fridge, too.
The only negative thing is that the WiFi connection in the apartment is not good and even worse in the room. But that was not a big problem for us.
Overall we had a very nice stay in Paris.
