best location, from CDG to hotel, we bought 2 days tickets from 1 - 5 Zone, we take RER from airport to chatelet-les-halles, then from chatelet-les-halles to hotel can by walk or by Metro, from metro to hotel about 3 minutes, we prefer by Metro since we have big luggage. hotel upgrade our room, one huge single King bed and I even find the slipper from the room, and the drinking (cafe, water, orange juice, Cola etc.) is free from the room, that's really wonderful room I met in Europe, the reception is very kind and humor and gave us many useful suggestions, from hotel to Louvre about 5 min. by walk, we spent three hours in Louvre, then found the wonderful chinese food near the Louvre, then take bus no. 72 from Louvre to Eiffel Tower, when we arrived Eiffel is about 22:15, but the street is still crowded, after Eiffiel, we take Metro to Triumphal Arch, it's very convenient, then walk through Champs-Elysees Metro 1 could back Hotel easily this location could help you find the real Paris easily
