Paris HOHO Bus

[NanaPapa]

We are staying 4 nights at DLP in May and we want to make a day trip into Paris and take the HOHO Bus to get acquainted with the sights.
Does anyone know how to get to the easiest/closest HOHO Bus stop from the train?
I guess I am asking for detailed directions please

Edited to add:
Never-mind, lol. I looked at the Rome 2 Rio site and figured it out

Great news

For anyone else interested, take the RER to Auber and the L'open tour HOHO bus office is situated across the road.
