Corrected entry: In the scene when Frasier and Martin are deciding where Daphne will stay, Martin mentions the study across the hall from his bedroom. Daphne eventually does stay in the study, which becomes her bedroom. However, in later episodes, Martin's bedroom is near Frasier's down the hall with the coat rack and Daphne's is near the piano. There is no room across from Martin's.
Corrected entry: When Daphne is hired, Frasier assumes she will live out. Marty wants to her live in and says she could have the room across from his. Throughout the series, Daphne's room is down a hall behind the kitchen and Marty and Frasier's rooms are next to each other in the same hall. Even in the first show, Niles takes Marty's suitcases down the hall behind the fireplace.
