We stayed here in late May. This is an excellent apartment for a couple or maybe 3 people in the center of Paris. Self check in was easy. The apartment is on the 3rd floor of a 4 floor building. The spiral stair case up to the apartment is steep and narrow. It is close to everything and well situated between main subway lines. It is a little touristy but it is still a neighborhood and the locals greet each other in the nearby cafes. The apartment is super modern/updated. Everything seemed to be in working order although the bedroom fan is past its prime. Sleeping is easy as the interior bedroom has no windows and is way from the street. The street is a little lane with stores and restaurants. Right around the corner are main boulevards so noise can be heard at night when the windows are open. The windows are new and when closed makes the apartment very quiet. There is an interior AC unit that must be vented to the outside via an open window. The apartment was cool when the AC was running and with extra fan in the bedroom running we couldn't hear much noise from the outside. The owners did not greet us but made sure to connect to a helper who was always quick to respond when we had questions. Check out was like check in but very easy. I would stay here again and I suggest it to anyone who wants a clean, secure, newer, apartment in a great location near Notre Dame.
