We had a great stay. The apartment was clean, well equipped and we missed nothing. The location was great - multiple metro stations nearby, bakeries and restaurants nearby, walkable to most of the place you would want to visit in Paris.
The door opens with a code, so it is great that you don't have to carry a key around. The host is responsive and provided detailed instructions for self check in.
Some nit picks about the place - the hot water takes quite a while to reach the apartment, so plan your shower ahead. We stayed for 4 nights and we had to do a bit of economy to make the provided bathroom toiletries work, but I believe upon request the host would have provided more.
