Looking for short term rental (~3-4 months)

Realise this is a bit of a long shot but thought I would ask anyway. Have a family friend who is separating from her husband. She has 2 young sons (both under 5 I think) and is looking for a short term rental for ~3-4 months. She is looking in and around the East Bentleigh area with a budget around ~$400pw.

She has already started the ball rolling but thought maybe somone knows someone or a contact with a short-term vacany that might be solved. Thanks :)
