We can recommend Stephane's place very much! We (a couple) stayed there for exploring Paris and for a conference. It is a cosy studio in a great location (very close to the metro station, the university and Rue Mouffetard, which is very nice for going out and finding a drink). There are places to eat and drink in the immediate vicinity. Stephane was extremely easy and fast to communicate with and was very helpful. Because the studio is on the third floor, and the window faces a small courtyard it is actually quite quiet. We would definitely want to stay here again.
