Pros (+) I arrived very early on a transatlantic flight and was allowed to check in early. The staff was friendly and always available. The room was very clean and well maintained. The location is on a side street and 20 minute walk from Montmartre.
Cons (-) Room 1 is located off the courtyard and says no smoking but the window opens directly onto the table where people are allowed to smoke. So the room often smelled of smoke.
