Marc was a fantastic host and his apartment was just as he listed it. It really is a very short walk from the Alexandre Dumas metro station (though warning, there is neither elevator nor lift at this station) and it is really convenient. There are some great restaurants nearby (I recommend Argana a lot!) and their lovely market is on Saturday and Wednesdays. The room at Marc's is really quite nice. The bed was very comfortable and the room is perfect for a single traveler. The bathroom is nice and clean and he's very generous with providing you shelf space. It's a really secure location with a locked gate and I felt very comfortable walking around his area at night. And, Marc himself is a great guy. He's very intelligent and witty and totally the kind of guy you want to hang out with. His English is very good and he is very accommodating. If you want to spend time with him, great, if not, he'll leave you be. If I come to Paris on my own again, I will definitely be staying with him!
