Hi ... which PG are you using ... usually have special spots where there's great views and lesser crowd... otherwise the usual would be middle of the street facing arc de triomphe, trocadero for the view of Eiffel (there's a carousel there too) the big wheel at place de la Concorde... opera garnier, steps on place de la madeleine, one of the 20 over bridges along river seine... the vendors stalls along the river makes a nice background too
