Small hotel with a beautiful interior, well located if you're doing the tourist areas of Paris. The Eiffel Tower is in walking distance, as is the Alexander III bridge and the Grand Palais. The Army Museum is right nearby, and there's a metro station across the street.
Except for the proximity to the Seine we found the area boring, though, and wouldn't stay there again, (it doesn't feel lived in), but that's not the hotel's fault, which we liked. Stay there if you expect to use the metro to go where you're going, avoid it if you want to have fun exploring the neighborhood.
And skip the breakfast, which is very basic, and go to one of the two cafes next door instead.
Minor drawback: This is one of those hotels where you leave the key at the reception when you go out, which is inconvenient and not very secure.
