Great location by the Champs Élysées neighborhood. Walking distance to Arc de Triomphe, Louvre Museum, and many other attractions. You have the metro a block away. If you need a taxi, just walk down to the block where Hotel Le Bristol is and catch one. This place is super safe to walk at night.
The flat was really accommodating for our family of three, including our nine year old who slept on the pull out couch. The flat was super clean. You have a little view of the Eiffel Tower from the balcony. If you want to do laundry you could, just make sure you don't try this the day before you're about to leave since getting the clothes to dry completely was a bit of a challenge for us. We had to air dry my husband's clothes. We're not used to having both washer and dryer in one. The shower head was a little tricky to work at first, but no big deal we figured it out after the first day.
Overall, a great experience. Would we stay here again? Certainly.
