I visited Paris for an expo in Porte de Versailles, and this was probably one of the best choice I could make. Great location for traveling by metro and taxi, lots of places to dine out, quite new facilities and very quiet.
My luggage arrived almost 2 days late by airline's mistake, but Veronique's gentle son helped out a lot with prompt communication to receive it safely.
Airport buses to/from CDG and Orly are about 4 minutes away by walk, so you don't really have to spend money on taxi.
