I was sceptical due to very mixed reviews but it was the only hostel left when I booked (end of August, fringe festival). It was totally fine though! Sure, the triple bunk beds aren't the best idea, but the room I stayed in was clean, I slept well, the room had an ensuite (shared with everyone else in the room ofc) and the WiFi worked perfectly. There are lockers in the room but they're riny, just big enough for a purse maybe but definitely not a trolley or backpack. And they require 1pound/euro to use. Luggage storage isn't even a separate room, just in the corner of the bar. Not as centrally located as many other hostels but not too bad either, it's like a 10/15min walk to the centre.
