It's so hard to tell from some of the writeups I've seen. I'll be in Paris May 26-30, and need a hotel with a safe, central location. I'm looking to stay on the RER line to CDG, so I don't have to tote my stuff around too much. And I don't want to walk long distances once above ground.
Any suggestions? Are there any stations with accessible access to the surface (I have a bum knee and walk with a brace, so I don't relish taking my bag up multiple flights of stairs).
