I was the first time in Paris ,and took really a long time to find the hotel. hier is some hints :you can take the RERB at the TGV airport , and you can change the RERC at the station "Saint-Michel Norte Dame". Please get off the the station "Grésillons" , choose exit 2, cross the road, pass the bus station than direct turn right, at the end of the street, turn right, walk along with the curve, than you can find the hotel. the people there are very nice, and the deparment hat the small kictchen itself, you can buy the the needed things in the surpermarket nearby the hotel and cook them by your self. in one word, I think this would be a better choice for you during your travlling, especially for a family !
