It was a very nice stay in Paris. The Hotel is close to the next subway station, so everything easy reachable. There was only one issue: we booked two different room types (one normal and one with more space). At check in we specifically took care about not swapping the cards as they were handed out to us. At the second day we realized that the more expensive room was the smaller one and after asking at the reception, they approved that the cards must have been swapped. Changing rooms was then unsatisfying for all of us. This minor issue is not worth rating the hotel other than 5 stars, errors can happen.
Besides that, the hotel is in a nice Paris-typical building with a lot of charm and we enjoyed the stay.
