This is one of the best hostels I've ever stayed and the staff couldn't be better! If you took the rock tour with Toddy's, it's a great value!
Location is great which is only 5-min walking distance from Southern Cross Station. The free Tram 35 is just next to the hostel. No free wifi, breakfast or locker.
The staff is good but the room is small and crowded. Other travelers just put everything on the floor. I booked two nights but had to leave the second day...
they provide free shuttle bus between hostel and airport which is great. if you stay over 2 nights, you can book a tour for free (worth of 28 Euro). The room is not that clean and the bed is not comfortable, but for 10 Euro per night, it's not a big problem. However, I had to take a cold shower one night which was terrible.
