Just had a one night stay here for the Blackmores Sydney Marathon event the next day. The rooms were neat and clean. Bathroom which was shared between us females was also reasonably clean.
As hostels go, Bounce is one of the very best. Clean, well facilitated and reasonably friendly, the premium you pay above the other hostels in the area is easily offset by the amazing transport access, being next to central station, and the security and comfort thats apparent from check in to check out.
Approximate cost: $35/night
