Overall, a nice stay. Pierre is very good with communication and most of it was fine. He tried his best to help us out when there were hiccups. The location is wonderful, close to many metro stops and under 10 minute walk to the Notre Dame and Saint Michel. It's a very quiet street, and there weren't any loud noises at night. You can, however, hear people flush their toilets and walk through the building. It's not terrible though -- and worth it for the quick walk from the building entrance.
I would say the major cons are 1) at the street level so you can't really open the sole window without people just a step away, 2) the wet laundry left in closets/bathroom so it attracts mosquitos when you open the window, and begins to smell + make the room humid, and 3) the hot water only lasts for about 10 minutes so you cannot take subsequent showers. We made the hot water thing work though and Pierre helped us to the best of his ability. Other than that, the lovely reading nook and the separate working desk are all great! The bed runs hot, but is a nice size.
