If you want an accommodation close (20-30 minutes walk) to the main sights in the center of Paris or to be close to many places where you can enjoy food - Joie is ideal. Although it is a small studio, it is quite well equipped. In terms of cleanliness, it is ok, but the attention to details would not hurt. As for the floor - you should know that it is theoretically on the 1st floor of the building, but the view from the room's window is more like that of a mezzanine (the garden starts with the window). We were happy that the heating of the room was supplemented by an electric heater :)
