Great location. Lovely flat, great building with mainly offices so tranquil in the evening. It is super close to the metro station, 5 min to the arc de Triomphe 10 min to les champs Elysees and 5 min from Ternes where you will find Fnac, Aldi, Monoprix, Celio, etc loads of shops and markets to buy food.
Flat is not big but it is not small by Paris standards, however, it is suited for a single person, 2 at the most. Was not super clean, bit of dust, hairs in the toilet, and a bit of mold in the shower, nothing major, and mainly the cleaning team's fault not Julien's. However, I know for a fact that if I had gone with my wife she would have been very upset with the cleaning and would have made me call Julien, so heads up if you are going with your partner! But overall a great place in an amazing location. ah and no, did not find any ants or any kind of bugs as reported in another review. Obviously, this was my experience and your mileage will vary.
