We had a great stay at the Hotel Royal Opera. The location is perfect, just a couple blocks aware from the Place de la Concorde. It is a middle point for all the tourist attractions. Our room was small but very clean and the staff were very helpful. We did not try the breakfast, but it is available for 5.50 Euros. There is a lift which is convenient when you are lugging up your luggage.
Directions: Take the Metro to the Madeleine stop. Walk down Rue Tronchet (street behind the Madeleine church) to your first street on your left, which is Castellane. The hotel is located on your left.
