Frederick was a pleasant host. We didn't hear much from him as he had just undergone surgery.
The location is fabulous! Walkable to the Seine, Louvre, Pompidou, Notre Dame. Lots of art books to peruse and lovely artwork throughout. His ideas for restaurants/patisseries and shopping are in an organized notebook.
After realizing I had forgotten something in the apt., he coordinated meeting up with his son a few days later to pick up my forgotten item. He was very accommodating and the extra effort was much appreciated.
