Seli's place is lovely to stay in. I find Australia to be safe, but there is a little bit of sketchiness in the area just near the train station. However I never felt unsafe. Lots of restaurants and gelato places nearby, and transport links were good. I used the train and buses nearby easily. You can walk to the CBD, which sounds long at 30 mins but it's a pleasant walk that can take you through a large park.
I would definitely stay here again if I was back in town.
