Good value option
I chose this hotel for a short, solo stay in Paris, where I wanted to spend relatively little but still be close to Le Marais and central Paris, have a comfortable bed, and not be awake all night due to noise. I have stayed in much fancier (and more expensive) hotels, and have rented large and beautiful (and more expensive) apartments in Paris. While those are worth the money if you want a special experience and you are traveling as a couple or family, this was just fine for a short solo trip where I was spending the majority of my time outside the room.
This hotel is excellent where it really matters, but does not offer the frills of the more expensive options.
Like many hotels in Paris, the rooms are definitely small. (I had a double room, but still barely bigger than the bed.)
The optional breakfast, served in the basement dining room, is OK, not great, although the coffee is definitely good. Pastries better than the eggs for sure (but who eats eggs for breakfast in Paris?). If you want breakfast before heading out it's fine, but it's not a place to linger.
Room decor is clean and pleasant, but unfussy. It is completely practical. Everything works, the shades do what they need to, the window is sound proof, the heat works, there is a/c.
You have to hand in your room key before leaving and pick up from front desk when returning. While it is a little annoying, I was never kept waiting coming or going, and it's good security.
