My family of 8 stayed for 8 nights in August. Two parents, four teenagers, a seven-year-old and two-year-old. The location, size of the apartment and amenities could not have been more perfect. Easily sleeps 8 plus had crib for our youngest. 3 showers helped us move quickly in the mornings. Bright, airy, spacious, clean and well-equipped. Wi-fi and TV with cable channels worked well. Kitchen had everything we needed to cook our own meals. In-unit washer and dryer worked well and were very convenient. Elevator-serviced 4th floor provided some nice views (my son could see top of Eiffel Tower from his bedroom) and helped with the noise, although you do hear the train if you have the windows open. We enjoyed being steps away from the Bir Hakeim bridge and its fantastic views of the Eiffel Tower. Public transportation was easy with the nearby Passy Metro station. Good restaurants and grocery stores within a 5-10 minute walk. Cute park and playground for the little kids only a couple of blocks away in this higher-end residential area. Trocadero plaza and Eiffel Tower only 10-15 mins by foot.
Katia was a great host. Communication was quick and efficient. Check in was smooth. Instructions and local tips made for a very easy stay. We landed on the hottest day of 2018, but Katia gave us instructions on how to use the air refreshers that were in each room to help cool down the apartment. Not the same as true air conditioning, but did help manage the heat somewhat. The apartment has a bunch of portable fans as well.
All in all, this was a perfect apartment for a week of living in Paris. Quiet, residential setting helped us relax a bit after a long day of sightseeing. Highly recommended.
