We had a nice stay in Sara's flat, which is spacious (for Parisian standards), bright and conveniently located if you have anything to do in the 13th/12th arrondissements. Bonuses were the excellent wifi signal, full cable, washing machine, dishwasher, a spacious elevator (a rarity in Paris!) and high security in the building. The apartment is also located right next to a small park, which was great since we were there with our toddler. When we had some small problems (e.g. with hot water, needing more closet space), Sara was helpful and made sure to try and provide solutions right away. The only drawbacks is that the apartment is not very child-friendly and does not have much space for your belongings, since Sara actually lives in the flat when not renting it out. But as mentioned she was helpful and made space for us as best she could.
