The Spa renovation began at the end of June. Whilst the Spa is closed (for 18 months), the hotel has opened a 1 million Euro pop-up Spa on the 4th floor, designed by Jeff Leatham. This pop-up is more luxurious than most Parisian grand spas, so, apart from not having an indoor pool for the next 18 months, I would not have any concerns whatsoever.
