We were initially a little worried that the room might be too small for us, but once we arrived and saw the room it was clear that was not a concern: the use of space in the room is very efficient and the high ceilings keep it from ever feeling cramped. Some reviews had mentioned that the bed is a futon, which is true, but I thought it was very comfortable all the same!
You couldn't ask for a better location: there are dozens of bars and restaurants within walking distance as well as easy access to the metro station. To get a sense, we were there for three days, visited the Eiffel tower, Louvre, Sacre Coeur, Rodin museum, and Medieval museum with only 7 one-way metro tickets each including our trips to and from the airport
