I stayed there for a week on September 19th and was very disappointed by the overall experience given the hefty price tag for a room.
On the plus side: double rooms are rather spacious and it's very conveniently located in the heart of Paris, with many nearby restaurants, cinemas and Gardens like the superb jardin du Luxembourg. However, the personnel forced me to pay the room upfront when I checked in as I booked through a website, without having had a look at the room first. I found this particularly un-commercial for a 4* hotel, a deposit would have been more easily accepted.The fitness equipment is old and there to justify the 4* rating, one bike and one treadmill from the'90s, the bare minimum without water bottles available unless you prompt the hotel staff to bring some. Access to the spa is also restricted as you need to book in advance and is only open from 8am to 8pm.
In a nutshell, very expensive for what it offers. I stayed in better places for half the price.
