Marc’s place is wonderful. The location is unparalleled (steps from the Louvre, easy access to various forms of public transit). Check in was super easy and straightforward. It is on a cute little street lined with shops and restaurants. The room is cozy and the bed is very comfortable. Everything was very clean. There is also a small coffee and tea area which was very nice.
I will say that there may have been a slight miscommunication in that the bathroom is not ensuite, and is also shared, but I had no trouble with it and did not even encounter whoever I was sharing it with.
