Our stay in Annie-Claire's apartment was awesome! It was incredibly spacious compared to other places we have stayed in in Europe, and the neighborhood is very quite and felt safe - the quietness was a nice change of pace from other more touristy districts we have stayed in! Although it is in a less touristy area, it was only a 5 minute walk to the Luxembourg train station (RER B line) and the Luxembourg Gardens! The apartment itself was very comfortable and clean with lots of windows. Also, the wifi was the best we had in Paris - we were even able to stream Netflix! Overall a fantastic place to live like a Parisian! I would definitely stay there again!
If I absolutely had to come up with a negative, it would be that the street can bit a little bit noisy - although we kept our windows open for cool air, which obviously let in more sound than if they were closed (when they are closed they do keep out a surprising amount of sound!)
