1. Location
The apartment is on a quiet street in the Porte Maillot area. It's convenient to the Metro (Line 1) as well as a bus (82) that goes to the Luxembourg Gardens, and the Arc de Triomphe is easily within walking range. Lots of restaurants within a 5-minute walk, including a cluster around the Palais des Congrès. My personal recommendations are La Gazette on Rue Duret, and if you are on the Left Bank then Le Christine on Rue Christine. Supermarkets, a boulangerie, a natural foods store and other shops are close by.
2. The apartment
Lovely 3rd floor flat with lots of space and a romantic ambiance. Living room, dining room, kitchen, bedroom (with sink and jacuzzi tub), shower room (sink, toilet and shower). All rooms except the shower room are spacious. A portable air conditioning unit in the dining room was effective; it kept the room cool, although not at the typical arctic temperature that one might be accustomed to in the US. We were there during some very hot summer days, with tempertures in the low 90s, and the apartment was comfortable. At night, opening the bedroom windows created some cross ventilation. [Note that when a place is advertised as "air conditioned" it does not necessarily mean central air; it could be a portable unit (and probably is, in older buildings) with a hose that vents to the outside, so if this is important to you then you should check in advance.] The apartment includes a washing machine, but we didn't use it. The kitchen has an oven and an electric tea kettle but not a microwave (or if it has one, we didn't see it or need it). The armoire in the bedroom has large shelves, which is convenient. On the other hand the shower does not have any shelves, and that's a bit inconvenient (note to self: bring a soap dish next time).
3. The hostess
Elisabeth was great. Our stay was literally a last-minute reservation (for various reasons we needed to cancel another AirBnB on the day that we arrived in Paris) and she got everything ready for us on short notice. She resides in the same building, and on the few occasions when we needed her assistance she was available immediately to help. Likewise when I sent questions by text or email she responded quickly.
4. The bottom line
My ladyfriend and I stayed here for 9 nights and liked everything about this AirBnB; it was good value for the price. We will return the next time we are in Paris.
