Oh Paris

I am travelling to Paris (France) for the first time next week. I have a reservation with the Marriott hotel whose address is given as "91, Blvd Charles De Gaulle, Colombes, 92700 France". Could someone please let me know the following:
1) How far is the above hotel from the Charles De Gaulle airport?
2) What is the transportation from airport to hotel? How much is the approximate cost?

I am going to Paris, France. I want to know if there is any cheap hotel That costs less than per night(single room)? Please give me the web address to check it out. Thanks.

Looking for a nice yet reasonably priced hotel near or in the centre of Paris, France for a young couple in early twenties. Somewhere that is near to the sights of attraction in the city and is near the train lines, restaurants etc. Anyone that has any recomendations on hotels would be a great help! Thanks
