The location is great, beds very comfortable. Access is easy with coded locks. We parked the rental car in front of the door into the courtyard while dropping off luggage. We were returning a rental car at the train station, but there is a parking garage nearby if needed. The apartment building lies directly over the subway line. The noise and vibration is not really an issue during the day, but might disturb light sleepers. We got used to it pretty quickly and I didn’t see a lot complaints about it from other travelers so it does not seem to be a big issue, but it needs to be mentioned. Very quiet otherwise. Lastly, the location cannot be beat. Metro stop nearby, taxi stand close (we used Uber which was great), walk to the Louvre, the Madeline Church, shopping, shopping, shopping.
