We stayed in Greg's apartment for five nights in September, and have nothing but great things to say! The apartment is very clean and equipped with fast internet, cable, and a lovely kitchen. Greg was very responsive throughout our trip and checked on us frequently, even from abroad. We had minor issues with the cable TV that Greg helped us troubleshoot and resolve immediately. The apartment is also incredibly quiet during the night (even my mother, who is very sensitive to sound, noted this), and located in a wonderful neighborhood -- walking distance to the Louvre and many great cafes and boulangeries.
