Police have described an attack on an elderly Sydney woman in her bedroom at a retirement village as an "appalling and cowardly act".

The 84-year-old came face to face with a stranger when she returned to her room at the facility in North Turramurra soon after noon on Saturday.

Police said the man, for whom they did not give a description, assaulted the woman before fleeing.

She is in a serious but stable condition in hospital with multiple injuries, including cuts to her face, chest and arm.

Detective Chief Inspector Luke Spurr said the victim and her family are in a state of shock.

"This is an absolutely appalling and cowardly act and let me reassure you these type of offences are uncommon and that police are doing everything in their power to fully investigate this matter and to locate the offender," he told reporters on Sunday.

The NSW force is appealing for information on the attack, particularly from anyone who may have been in the area and seen something suspicious.
