We didn't get to meet Ji but her associate was there to greet us and store our luggage until check in time. We were also able to leave our luggage on our last day while we visited the city some more. Ji's flat is not close to the "main" attractions but very close to Montemarte district, which was amazing. The subway is a 5 minute walk and gets you everywhere in Paris with ease. The studio was smaller than I expected from the pictures, but clean and had everything we needed for our stay. Ji had great communication.
