Maud's apartment is the dream. Book it now. The apartment is so comfortable, clean, quiet and pleasant to spend time in. We made a point of having slow mornings at the apartment and taking breaks there in the middle of the day because it enhanced our time in Paris - it was so much more than just a landing pad.
We have been to Paris several times and this was by far our favorite place to stay. The location is ideal - the neighborhood itself was one of my favorites that we visited (great food, shopping, few tourists) and it's also near many metro stops. The couch and bed were both super comfortable, and we enjoyed watching Netflix on the TV at night. There's plenty of storage in the bathroom and bedroom, and the shower was great w/plenty of hot water.
And finally Maud herself is wonderful and so sweet. She's excellent at communication and proactively gave us tips on how to get around and where to go. She made us feel so welcome in her home.
