This apartment was a bit of a splurge for us; but worth it in so many ways. The place is big (esp for Paris), the two bedrooms are on opposite sides of the apartment, separated by a nice living room with a very comfortable couch, and a large bathroom off the living room with a large wonderful shower with instant hot water. Comfortable beds.
The neighborhood is definitely upscale, but Josephine is just a block away for very reasonable breakfast and sandwich to takeaway for your day. The Arc de Triomphe is just a few blocks away -- try to time your nighttime climb up with the lighting of the Eiffel Tower. Pages 116 just to the left downstairs was wonderful -- three of us shared the delicious euro 116 meal for 2 and were more than full. If you come with kids Villa Sophia 53 Rue de Chaillot serves a variety of pizza and has friendly service [and Adrien's is the perfect place to bring the kids given the apartment size and layout].
Several Metro stops are just a few blocks away, George V on the Champs Elysée is on Line #1 which goes to many tourist locales.
Communication was very very prompt, and check-in was smooth despite a flight delay. We'd definitely return.
