Book this place. The location is walkable to the the Champs De Mars (great for scenic picnics in front of the Eiffel Tower). There is a bomb pizza shop next door and the rest of the city is accessible by metro which is just a few minutes' walk away.
Deborah and Thomas are wonderful hosts. Very hospitable and communicative. We had a minor hiccup with the electricity and they were very attentive to helping us get everything in working order despite being on vacation themselves. 100% booking here again whenever we return to Paris.
