The apartment is perfectly located in a quiet rue off the nearby main street, and connects with a pedestrian-only street lined with artisenal shops of all kinds: boulangerie, patisserie, produce, bistros, and everything else you can imagine in Paris. At night it's quiet and during the day it's full of life.
The apartment itself is light and airy, and more spacious than most Parisienne apartments for the price. If you're musical, there's a piano (properly tuned) and a guitar that can be used. If you want to cook, there are sufficient pots & pans but the induction stove is typically rudimentary so it's best to do what Parisians to and eat out at one of the local restaurants.
For reasons I've never understood, the majority of AirBnB properties in Paris tend to be full of the owner's possessions, as if they've stepped out for a few minutes and naturally have left all their things in situ. This apartment is no different, which means it's tricky to find space in the fridge and freezer, and very tricky to find somewhere to put one's clothes. But this apartment is no worse than others in Paris - it's simply something to be aware of ahead of time, as you'll likely find yourself unable to unpack and will have to live out of your suitcase for the duration.
I've usually stayed north of the river during my many trips to Paris but discovering this apartment has utterly changed my default preference. The location is ideal, the local shops are enchanting, the metro (Ecole Militaire) is 120 seconds from the front door, and the ambience of the apartment is such that one never wants to leave.
