I stayed at the Sofitel Porte de Sevres a long time ago and hated it--horribly situated, utterly devoid of charm or character, lousy croissants (in Paris, no less!) for breakfast, and indifferent service. BUT, they now have some primo properties there (the Astor is supposed to be wonderful, and several major divas love the Scribe), so it probably depends on which one you're at.
