We had a wonderful stay at Sophie's for a few-day visit to Paris. The studio was easy to find and located in a safe area close to a few metro lines, bakeries, and grocery stores - it was a single train ride from CDG airport. Our flight was delayed but we were able to reach Sophie by phone after arriving later than she was expecting and she came quickly to meet us - otherwise she responds very quickly on airbnb.
Sophie thoughtfully asked us if we needed separate beds and brought up a cot for us which fit perfectly in the cozy studio. She also left us lots of snacks and essentials, and lots of tips for getting around Paris. The Wi-fi was tricky to set up and seems to work best if you first do a one-time pairing over Bluetooth with the box. It was very hot during the time we were there but both windows can open to circulate air. Cooking was easy with the available cookware and kitchenette.
Altogether a cozy space with all of the essentials. Recommended.
