We had a great stay at Sophia's apartment. We didn't meet her because she was away for the holidays, but she was incredibly responsive to emails and when I asked for a dinner recommendation for New Year's Eve, she not only suggested a great restaurant, but she made the reservation for us. Her apartment was spacious and comfortable, and had one of the largest bathrooms I've seen in a Paris apartment! It's on the third floor of a walk up which was a little challenging with our suitcases, but we managed. The location is great, very close to a lot of tourist destinations, but it didn't have the neighborhood feel that you might get in a more residential area, with a neighborhood bakery and such. It was very close to the Roissybus, though, which made getting to and from the airport incredibly easy. Overall, this was a great place and we would absolutely stay here again!
