I've stayed at Hotel l'Empereur and I recommend if you stay here you pay the difference and get one of the view rooms. The rooms on the 5th floor have teeny balconies, others just have floor to ceiling windows. The gold dome over Napoleon's tomb is lit at night and it IS gorgeous. I stayed at this hotel on a Rick Steves tour and then again last year on my own. The rooms are very nice, staff is terrific. The breakfast room is on the small side but there is a nice selection for breakfast and one of the cool orange juicer machines that juices fresh oranges. This is on the corner of a fairly busy street but I have not noticed any street noise when I've had the windows and drapes closed. I did have an odd arrangement last time where there was a floor to ceiling window in the bathroom - it had fabric covering it but I was pretty sure you could be seen at night with the light on. Decidedly quirky.
I've also stayed at Hotel du Champ de Mars which I think has a room or two with maybe a teeny bit of a Tower View. Nice rooms, very Parisian. Breakfast room in the basement, and you are served a roll, croissant, yogurt, fruit and coffee or tea.
I've also stayed at Hotel Londres Eiffel which does have some tower view rooms listed on their website. My only thought about this hotel is that I thought there was a lot of traffic noise. I was not in a view room just on the 2nd floor but facing the street and the direction where you would see the Tower. The hotel is located near a corner of Rue Saint Dominique which carries a lot of traffic. Hotel was nice, is used for some RS Best of Paris tours. Small breakfast room but again nice selection. Very nice staff and a resident dog. Well, he doesn't live there but comes during the day. Yellow lab I think, hahaha.
