Le Meridien Etoile is NOT a hotel for honeymoons (Le Meridien Bora Bora would be a better choice, for those who like perfect islands).

The Westin Paris is definitely a better choice - I will be there on Wednesday evening ......... alone, in my Ambassador Suite, but will have friends visiting.
The Hyatt Vendome, which is quite close, is even a better choice (stayed there last year).
