bus stop nearest Hotel Leveque

Actually, Bus 69 (it leaves from the Eiffel Tower area and goes to Pere Lachaise cemetery) stops on Rue Saint-Dominique on its way to Pere Lachaise (goes right by the Louvre) and comes back a slightly different way.
To catch it going away from Eiffel Tower, turn right when you come out of Grand Hotel Leveque, cross rue de Grenelle, go 1 short block to rue Saint-Dominique, turn right and the bus stops a few houses down on the right. Coming back, it stops at the corner of rue Cler and rue de Grenelle, turn left on rue Cler and you're practically in front of the hotel. You can go to Notre Dame cathedral on this bus. Coming back from Notre Dame, you'd have to catch it on rue de Rivoli, where it goes past the back of the Louvre, crosses the court-yard and goes on its way back to tour Eiffel. This is a great sight-seeing bus. I took it several times.
