I cannot reccomend Matthieu enough as an airbnb host: months before my trip we were in touch, and he was incredibly amenable to my requests and helpful in coordinating arrival and departure. He was courteous, gracious, and thoughtful thruoghout our stay, and also readily available to answer questions or assist.
The apartment is small, clean, cute, and functional; it's a loft-style, but be mindful that the second 'story' has a low ceiling. All amenities were provided and Matthieu walked through everything with us, including maps and nearby food spots, grocery stores, etc. There is a Metro station literally right outside, and this made travel throughout Paris a breeze! Though it is a busy street, noise from outside was minimal. However, it is an older building and sound does travel from nearby apartments and the hallway- I'd advise earplugs or headphones. My Mom took the upper bed and I took the couch-turned-bed, and we found both to be comfortable. We used the kitchen for lightly prepped meals, and pletny of tea and coffee was provided.
For a simple, fairly budget stay with easy access to Paris and an unrivaled airbnb host experience, I'd definitely recommend Matthieu's apartment!
