I would highly recommend this place to anyone visiting Paris. It is very comfortable and well located.
The check-in is done with key-boxes which makes it super convenient so you don't need to wait for anyone to meet you.
Please consider one of the rooms is in the basement and you have to go down some narrow and a steep stairs which might be a problem for older people or people with accessibility issues.
Also the basement room's bathtub is inside the room (which actually looks cute) but it doesn't have doors or a curtain. Also it doesn't have a head shower so wouldn't recommend this room if you're not used to taking baths.
It is a great place I would definitely go back there!
