This flat is huge by Paris standards, which is such a treat for any long-term travelers like ourselves. You'll have space to unpack and do your laundry - a laundry rack is even provided for you (look behind the couch!). The tall ceilings and large windows open out to the street and let in the sounds of Paris along with a nice breeze. You won't necessarily need the latter because the aircon in flat (2 units) is wonderful - we so appreciated it during the heat wave this summer. We cooked many times in the unit and found the included kitchenware sufficient.
There were previous reviews mentioning sex workers on the street. While this is true, they never approach you and I wouldn't have had a clue about their business unless it had been pointed out to me. Safety is not an issue, especially with the multiple doors and digital lock for the unit.
Our only complaint was regarding the cleanliness of the unit, which Laurent quickly addressed on our second day in the unit - generally, his response time is very fast! Note that the photographs in the listing don't include the current wear on the living room furniture.
