Dozens of beds (in the form of triple-decker bunks) in one huge room sounds overwhelming, but the common areas are separated, so nights were peaceful.
This hostel was also unusual in that it's run by some sort of Christian youth group, staffed by Brits and a few Ukrainians somehow recruited. Other than a Bible or two sitting around, and the logo being the Iwo Jima image with the flag replaced by a cross, no religious messaging.
The age range is probably the least diverse of any hostel yet -- no families, no senior citizens -- but the language mix is huge -- Chinese, Russian, Italian, French, German, etc.
The day we arrived was the famous twice-weekly waffle night, where the staff make Norwegian waffles served with jam and a weird cheese.
