Stephanie and Xuan's place is a hidden gem, tucked away in an inner courtyard. It is very close to two metro stations (one of which is also an RER/regional train station). There is a great market-pedestrian street a few blocks away (rue Daguerre).
It is surprisingly spacious with three bedrooms and 1 1/2 bathrooms, a full kitchen and living room/dining room. All the amenities worked well.
The hosts provided useful local information and were extremely responsive and helpful.
Note: It would be challenging for a person with mobility issues to stay there (quite a few stairs required to reach inner courtyard).
