Describe Montag's bedroom. Is he happy?

From the text:

"It was like coming into the cold marbled room of a mausoleum after the moon had set. Complete darkness, not a hint of the silver world outside, the windows tightly shut, the chamber a tombworld where no sound from the great city could penetrate."

"The music was almost loud enough so he could follow the tune. He felt his smile slide away, melt, fold over, and down on itself like a tallow skin, like the stuff of a fantastic candle burning too long and now collapsing and now blown out. Darkness. He was not happy. He was not happy."
