As all the aforementioned comments below describe, William and his wife were very charming and hospitable. The apartment is lovely, like a museum. The location was good, nearby the subway and we highly recommend getting the Navigo pass. The patio was beautiful, and we loved the view. They also gave an electric kettle in our room for tea or coffee. The cigarette smoking was bothersome, but as long as our door to the bedroom was shut, the smoke would not get in.
