Had a long flight and when I settled in at 12pm I was absolutely ecstatic that there was customer service 24/7. I did not try the breakfast but I heard it was amazing. Florian responded back immediately and the hotel will hold luggage even after you have checked out. This really helped me when I decided to come back into the city a day after my stay. I would 200% recommend this to anyone trying to see Paris and wants the quaint of living in a lavished hotel.
