Very comfortable and located in easy walking distance to two Metro lines. You’ll be in a real Paris neighborhood so the plus is you get to experience life as a local in the nearby cafes and restaurants. Down side is you’re a 25-30 minute Metro trip from the major museums and sites in the center of Paris. That said, the Metro trains run every few minutes, are very reliable and cost is very reasonable, particularly if you buy a multi-day pass or a carnet of ten tickets. Sylvie is a great host providing tips about local restaurants, etc. and responding promptly to requests. Building has an elevator which is useful since flat is on the fourth floor.
