Simon was a great host. He was communicative and quick to respond. The flat is modern and has everything you would need to relax and enjoy a visit to Paris. The main metro line is right around the corner from the place, and you can get to anywhere in the Paris city center from there. You have tons of shops, restaurants, and nightlife within walking distance.
If you are coming from CDG airport the train line comes out at the Westfield mall and from there its about a 10 minutes walk down the main street. Takes about 35 minutes to get to the airport from his place by train.
I would reccomend this apartment for a solo traveler or couple looking to visit Paris.
