We stayed in the Hotel Louvre Marsollier Opera. It is on a quiet back street between the Opera Garnier and the Louvre, as the name implies. We were well satisfied and would probably stay there again. It is of course a budget hotel and doesn't have some of the amenities of a more expensive place

It gets mostly very good reviews on T/A.

Thank you for the help Travelnut and Joetro. I did read the reviews on T/A. I feel comfortable with my choice.
