 It takes about 15 minutes to Porte Malliot where the Air France express bus drops you off from CDG The nearby Metro stations Argentine and Perriere are also a 10 15 minute walk away Therefore budget for it 
 Staff is very cooperative and speaks English which is very helpful in a city like Paris They are eager to help if you have questions about where to go look up Google maps etc WiFi in the hotel works well we got good high speed connections most of the time
