This once elegant foyer retains the vestiges of its former beauty. A deep crimson rug lies across the darkened rosewood planks, softening visitors' footfalls. Dark-red velvet curtains hang from dust-covered windows, preventing passersby from looking in. The front door has been nailed shut, rendering it useless as an exit. A wide staircase curves up to the railing at the second floor landing.
