I traveled to Paris with my husband and 2 teenage sons in December. Marie was an excellent host - she was professional, responsive, and communicated well. The apartment is on the ground floor and located on a non-residential street in a garment/textile neighborhood. It appears that the space was originally a storefront that was remodeled to be a rental apartment. At night, the street feels a little dark but the neighborhood seems reasonably safe if you follow general common sense precautions for a tourist. The location of the apartment is within 2-3 blocks of Rue Montorgueil which is a fantastic pedestrian road filled with many delicious shops for a foodie. The apartment is also close to 2 metro stops and made for easy exploring of Paris without being surrounded by hoards of tourists. The apartment itself was clean and perfectly adequate space for our family of four. The ground floor can be noisy because it is poorly insulated from street noise.
