Guillaume's place was great. It's a cozy little flat near the river with a great view. We were a bit nervous about the pull out couch but it turned out to be very comfortable so don't let that stop you from staying here! Although cozy, the apartment was great for what we needed on our stay--a place to lay our heads while we weren't out venturing in Paris. Check in was our only qualm--we weren't able to check in before 2pm (due to cleaning schedule which is totally understandable) but put a hitch in our schedule as we arrived to Paris around 10AM. If you arrive early, you'll need to store your belongings in the train station or other--just something to be aware of. All in all, it was a great stay and we would stay again :)
