We really enjoyed our stay in this lovely apartment. The location was fantastic, and we enjoyed breakfasts and dinners at restaurants only steps from the front door of the building. We also had multiple metro locations nearby and were easily able to navigate Paris from this location.
A couple of notes (which we knew from reading other reviews but wanted to point out) - while there is a washer, you will have to hang clothes to dry. This was not a problem for us - the unit came equipped with a hanging rack, and the heated towel rack in the bathroom made drying cotton items like socks and pants quick and easy.
The kitchen was well stocked and there was a two-burner cooktop, but there is no microwave or oven. We were able to make our kids ramen one night when they were tired of eating out, but it did slightly limit our eat-in options when they wanted pizza but we had no way to cook one. We did love being able to have cereal and milk on hand for quick snacks and breakfast for the kids, and there was nothing lacking that made our stay any less incredibly.
We would highly recommend this location for a family or group on the go. It was also nice to have an elevator when we had to get the luggage up or down from the apartment. As for the reviews that were concerned about how to retrieve the key, I found the location to be mere steps away in a nice market, and it took less than 2 minutes getting the keys from start to finish.
