Our family of four (two adults and two kids ages 6 and 8) had a very comfortable week-long stay at this apartment. It's located in a lovely neighborhood with several delicious bakeries and grocery stores within a five minute walk. There are also many restaurants close by, including a delicious Algerian spot around the corner. Several metro stops are located within a few minutes walk.
For a week long stay, it was great to have the dishwasher and washing machine (which includes a dryer setting).
The apartment is clean and provides sufficient space for everyone to feel they're not living on top of each other. Of note, the basement bedroom is slightly damp, though there is a dehumidifier running at all times, which helps. It was definitely sleep-able.
The apartment managers are friendly, helpful and very responsive.
