Though we never met the lovely host, they use a bnbsitter service, the communication with them is always prompt and easy to understand. They have a manual in the room which comes in a few languages, which would be helpful to guests from other nationalities. The place is very near La Motte Picquet Grenelle metro, which has 3 lines serving them. Just take note there are a few steps (about 5) and if are on a wheelchair, it might be inconvenient. (There is a wheelchair lift, but it was on maintenance when we were there.) A great place to stay!
