Los pasillos de su gran casa le parecían lúgubres, sólo porque no sonaba en ellos el estrépito de las pataditas infantiles.

The hallways of their large house seemed gloomy to her only because the patter of little children's footsteps no longer resounded through them.

Or else 'the patter of little children's footsteps...'

"his" is correct, but wouldn't "their" or "her" be more logical in the context ?
While you are at it, I link "clamor" with voices rather than footsteps. 'scurry of ..." ?
