Elodie's studio is pleasant and ideal for a short stay in Paris. It's in an excellent location, safe and central, on a quiet street yet close to restaurants, bars and beautiful sights (walking distance). There are a few metro lines nearby too. We loved having a kitchenette, so we could keep groceries there and at least have breakfast "at home" every morning. It's very bright and airy, and was impeccably clean and well-maintained. We did not meet Elodie but she was very responsive, and had people bring us what we needed right away.
For a small fee, we were able to get a baby bed set up in the studio, which was very handy for our little one. Keep in mind that the place is super tiny, so with a baby bed there was not much room left to move about. We were mostly out and about during our trip, so the lack of room was not that big of a deal.
I would absolutely rent out Elodie's studio again in the future, but perhaps not with our baby (unless it was just for a night or two). It's a little gem in the heart of the city.
