We did not meet Etienne in person, we collected the keys from her friend at another office place. The check-in process is great if you did not travel with suitcases. We are 3 with one suicase and one bagpack each, 5th floor is killing us, those travel with baby and lots of stuff need to pay attention to this. Other than that, the flat is awesome, good enough space for 3, fully equipped kitchen for us to cook simple breakfast every morning. Simple 3 mins walk to a busy metro station, I dont think there's anywhere else better quality and location with this price in Paris. I keep in touh with the host for the 5 nights stay. If any problem she tried to solve it for me. I think overall this is a very happy experience.
