The room is perfectly situated. You can see the Eiffel Tower from the window. The host, Reza, is very welcoming and nice.
However, you should keep in mind that the room is a part of residential apartment and it is not always very clean =)
Also, the building is pretty old and the floor is creaky.
Overall, for a short stay in Paris with a minimum of things (like a backpack) this room is great.
