Niles owns an apartment in a prestigious Seattle apartment building called The Montana. Upon the family's first visit there, Niles notes that the doorman let in Frasier because he knows him, as the Montana doorman lives in the Elliott Bay Towers – Frasier's building.
The door opens up unto the combined living- and dining room, with a fireplace and a door adjacent to the dining area which leads to the kitchen. Between the fireplace and the dining area is a staircase unto the landing of the 1st floor. To the left of the entrance is a hallway.
Contains multiple rooms, including Niles' bedroom, a gift wrapping room, library and study. Martin, while lost, also found a path unto another landing with a bookcase harbouring a secret door, which is open by pushing the bottom of the Mrs. Dalloway. The landing atop the staircase leading from the living room also opens up unto a balcony.
A second staircase leads up unto the 2nd floor, although the layout goes unmentioned
