Any recommended a Parisian hotel facing the river Seine (and if possible below 150 euros for a double).
Merci.

Just to save people some time, these were the recs given to you on TA forum:

You could try:
Hotel du Quai Voltaire
Hotel Eiffel Seine
Whatever Hotel Nikko is called now (I think it's a Novotel)

Try some of the smaller hotels ON the Seine, staying on the islands. Hotels are small, and may be your budget. Areas are close enough to walk to Notre Dame, Louvre, and LQ, but area very quiet at night.

Hotel Les Rives de Notre Dame and Grand Hôtel de Champaigne are two possibilities. Both get stellar tripadvisor reviews but over 150 Euro, however. Paris hotels facing the Seine don't tend to be in the budget category.

bardo is right on that one -- Seine views in hotels are on prime, expensive property, and there aren't very many hotels even with Seine views, let alone budget ones. I think the Quai Voltaire is your best bet (and even they don't have views in a lot of their rooms, as I understand it).

We stayed at Hotel du Quai Voltaire. DON'T!! Rooms that face the Seine are hear all street noise,especially motorcycles and rooms that don't, face an airshaft. R. Wagner stayed there and in his letters said, "I'm in dire situation, no money, living in squaller (sp?)". Stay elsewhere in Paris.
