I was there earlier this year. It was a nice enough place, if a little different to what we may be used to. The Club in London has better rooms than the one in which I stayed, though the whole place was being refurbished (including the bedrooms) at the time. It has the world's smallest lifts!!
It is located at 8, Place Saint-Augustin, 75008, Paris. The taxi fare from CDG was about £30 which we found to be well worth the money, compared to the hassles of the underground with luggage etc. My wife and daughter and I all shared a room, which was no problem with the club. The nearest underground station is only yards away and is called St Augustin. Reception will supply you with a very handy map which will certainly help you get around. Hope this helps.
