Lisa is the best host. Our family had a great time in Paris in no small part because of her and this lovely apt. Great location! We chose it bc it's a short walk to Notre Dame and Sorboure Univ/Pantheon. Taxi from CDG ariport to the apt was 58 eur. Train from the apt to CDG was about 10 eur per person. Yellowline (10' walk from the apt) to the Louvre, Champs Elysee... is the nicest, cleaniest metro line in town. The walk from Arc de Triumphe to the apt is downhill, very pleasant. If you're tired, just hop on the metro. By a stack of 10 tickets to get a discount. If extra, donate to charity on the train to the airport.
