Our stay at Marion's place was perfect. Communication was excellent. While Marion wasn't there to meet us personally, we had a warm welcome from her friend. Checkin and checkout went smoothly. The location, while a little bit away from the main attractions, was perfect for us as we like to walk and could reach The Louvre in about 25 minutes and Sacré-Cœur in about 15 minutes. The metro is steps away from the flat so it's possible to get anywhere very easily.
