Comparing this hostel to hostels in Berlin or Prague, it was definitely not as nice. It was huge, with around 500 beds. Breakfast was decent however. As for hostels in London in was rated very high and for the price of it it was very reasonable for what you got. Great place to meet people and the bar was pretty busy at night.
Great place to go if you're looking for a stay that's a little bit more relaxing and low key, but still right in the heart of the old city.
