We had a very pleasant stay at this apartment. Alexandre was there to greet us at the apartment, was flexible regarding keys and check in and check out time, offered some advice on neighborhood recommendations, and was responsive throughout our stay.
The apartment is of a modest size but in a very social and active neighborhood: bars, restaurants, shops and coffee are only right downstairs, and it is 5-10 minutes walk from several metro stations. Do note that the street is lively at night, especially on the weekend. Because of this it seems to be a safe and pretty cool neighborhood, but you may hear some of the noises of people walking about on the street. This was not unusual or excessive for a central-urban location and the apartment itself does not face the street, so it did not disturb me at all...but I do live in a city too.
The amenities were as-promised including reliable wifi internet.
I would absolutely stay here again on my next trip to Paris.
