Nice hotel, especially for middle of paris, walking distance to seine and notre dame, affordable, modern
Went to gym in the morning, Sauna had been running all night, so not high on environment
Did not use breakfast, basic continental breakfast
Gym is reasonably equiped, I do yoga, the floor was so slippery it was impossible, there was yoga mat but was also sliding on the floor, gave up
Bit of noise from the street in hotel room (first floor facing the street)
