This apartment was perfect. We were able to fit 6 people comfortably with room for more on the pull-out couch. Check-in and check-out were seamless which was great after getting off a 7+ hour flight, and they even let us check-in early! It is in a great location, walking distance to one of the only pedestrian areas in Paris, with great shopping and restaurants. There was only one bedroom with a mirror, but two bathrooms with mirrors, so we shared. Potentially would have brought a portable mirror for makeup, hair, etc just to free up the bathroom for others. We had some issues with the door to the apartment, but eventually figured it out (pull towards you after you unlock). Also, there was construction in the entrance and stairwell, but it did not affect us at all and was not a problem.
All in all, this was a great apartment and we had a wonderful stay!
