I stayed at Audrey's for 11 days and really loved it! it's a hostel with only 8 rooms, so it wasn't crowded and was actually quite peaceful . The bed was very comfortable, great firm mattress and comfy pillow. There were 2 well-maintained bathrooms with free shampoo, body wash and toilet paper. There were also a washing machine and a great drier for $4 each per use.
The best thing about the place is its location - super close to the Southern Cross train station and malls, there's Coles supermarket down the road and plenty of cafes. I especially loved George's paninis, Brightside bagel place and Higher Ground café near by.
As this hostel is next to a couple of bars, there was some loud music playing on the weekends, you can also hear the road, but I personally wasn't super bothered by that.
I recommend Audrey's place to anyone who's after a central, affordable and safe place to stay in the city :)
