Unless you know your way around Paris, or are willing to study up on the trains, Metro, and buses, I think you would be better served by taking a taxi. It wouldn't be difficult to actually find your hotel if you had some experience with the various changes you need to make, but assuming that you are jet-lagged from an overnight flight, learning about procedures and routes of the RER, the Metro, and Bus Route 27 won't be fun. Check the threads in this forum for taxi details. Also, if you get a good guidebook, like the RS 2018, things might be a bit easier.
