My wife and I stayed here as part of a 50th birthday celebration and we spent two days at the French Open. The hotel is in a great location as mentioned by others - great sites nearby included the Eiffel Tower, Napoleon's tomb, and the Rodin Musuem (my personal favorite as much of the work is outside with some incredible pieces of art). The most convenient Metro for accessing other parts of Paris is La Motte-Picquet-Grenelle - which is about a half mile walk from the hotel. This walk takes you by the Eiffel Tower and Ecole Militaire so it was not a most enjoyable walk. Hotel is also close to some very good restaurants and the front desk can help with recommendations.
I was a little nervous about the Classic room that we booked as I was worried it would be small and uncomfortable. The room turned out to be just the right size with one of the most comfortable beds I have ever slept on. The room is very quiet at night and the night darkening shades work extremely well. Skip the view of the Eiffel and go for the Classic rooms located on the interior of the building if you want a good night's sleep. See the pictures I've attached.
Breakfast spread was very good and the staff was friendly. We would definitely stay here again.
