I had mixed feelings about this apartment. It is well furnished and a nice size for two people, the apartment well laid out. Most of the basics are provided (although as some have noted, more pillows and covers would be nice.) It had one of the largest refrigerators of any place I stayed in in France. The location is great, access to the metro, etc, and the grand epicerie of the Bon Marche is really fabulous.

The downside does have to do with noise and privacy, and here this is pretty subjective. People run a gammut on noise tolerance, but if you are on the low end, this is probably not for you. You are in a courtyard and sheltered from the major bustle of the nearby street. However, you can hear it every time someone goes through the courtyard, opens or closes the door to the street, etc, and as people noted, you can also hear dimly the frequent rumble of the metro and it can set dishes or other objects rattling. The windows are single pane, and the wooden door is rather thin without much of a seal, so you are not very isolated from that courtyard at all. Many people would not be bothered by this, but I'm more on the sensitive side, hence my mixed feelings.

One other thing, when checking in, be careful to note that you go to 6 Rue Babylon to pick up the key, etc, even though the apartment is at 4 Rue Babylon. Benoit's instructions pointed this out, but it's a detail that is easy to miss since the numbers are so close.
