Xavier's apartment is fantastic and one of my new favorite places to stay in Paris. Central location, minutes away from two main metro and train stations and surrounded my great restaurants for breakfast ( check out Claus) and dinner (my fav in Paris Louise for its home style yummy food). Shopping and main tourist attractions are also only a short walk away.
The apartment was clean and modern, with a great bathroom, great curtain's also kept the room nice and dark (important in Paris summer as the sun sets late). I would highly recommend this apartment.
