Elderly mother relocating from Coffs Harbour to Newcastle

My father passed away in August, my 82 year old mother is very keen to vacate Coffs Harbour. She has her sights set on Newcastle. What would be an affordable, safe location in proximity to hospital/nursing homes in Newcastle please. I'm guessing a 2-3 bedroom unit for rent - somewhere not too hilly as mum uses a wheelie walker. Any information, suggestions for real estate companies to contact or anything else you think might be useful information will be greatly appreciate.
Thank you kindly in advance!
