There are two Ibis near CDG airport :
- first one is Ibis Paris CDG airport which is 2 minutes walk from terminal 3 (The one Goldorak is speaking of)
- second one is Ibis Roissy CDG Paris Nord : I understand this is the one sfo is looking for.
For Ibis Roissy CDG Paris Nord, you have to take free shuttle services : blue line (there are 3 lines : pink, black and blue). The pick-up point in Terminal 2 is the bus stop nearby the TGV-RER railway station Aéroport Charles de Gaulle 2, proceed at Level 5.
