Jules's place is a very lovely, large apartment in a great part of Paris. It's their family home so don't expect the more hotel-like AirBnB - this is where they live full time. As such it was well stocked with everything we needed. We especially appreciated having toys for our young children. We are a family of five and had more than enough space - the apartment is quite large, with three bedrooms including a generously sized master bedroom, laundry (with a dryer! virtually unheard of in France) and two bathrooms (one toilet but two showers).
The neighborhood is fabulous. You are right on the line 7 and close to the border between the 5th and 13th arrondissement. There are tons of great restaurants and the wonderful market street of Rue Mouffetard is a few short blocks away.
If you are lucky enough to get a chance to stay in Jules's apartment, we highly recommend it.
