We had a wonderful stay in Paris, using Alain's apartment as our base to explore this lovely city. While we walked most of the days, the Port Royal RER station is literally around the corner. It is so easy to just get the RER B train from CDG if one is traveling light! The apartment is comfortable, and spacious enough for 2 people (European style, the bathroom can only take 1 person at a time). The kitchenette is fine for simple meals, warning up etc, large fridge (much bigger than most in Europe), toaster, microwave and electric cooktop (we didn't use latter). The living room and TV are fine for relaxing on the sofa, can watch French language TV). The wifi is excellent. All basic amenities are there, but bring your own bath and toilet soap.
