If Antonio's place is available for your desired dates--BOOK IT. This was one of the best airbnb experiences my friends and I have had. Which is extremely rare for Paris too.
It was a beautifully decorated place with comfortable areas (couch, big kitchen table). The bathroom is tidy, has a great shower, and needed products. The beds were both comfy (a double and a sofa bed). This isn't one of those quick flip, sterile places. It's well loved and feels very homey. <3
Location wise: I would say the best you can get in Paris if you're looking for less-touristy, super cool, artsy areas with great shops. You're about a 5minute walk from the Marais which provides trendiness while still feeling like an approachable Parisian village.
An absolute must.
