I stayed at this youth hostel as part of a school group, after reading the reviews on here I was initially quite worried about visiting the hostel but i can honestly say it wasn't that bad.
I stayed in a room of 10 and it was a good size with two bathrooms which were incredibly useful for a room of 10 girls, they along with the sheets and the room in general were clean enough.
The breakfast wasn't the greatest breakfast I've ever had but it definitely filled a hole and the packed lunch provided was actually really nice.
The previous complaints about the lack of use of the lift is in my opinion pretty small, we were on the second floor and I can honestly say that I didn't find the stairs a problem. I believe that the hostel is close to Rotherhithe overground station but we used Canada Water tube station which was a very pleasant 10 minute walk from the hostel.
In short, don't be too put off by the negative reviews, this hostel is pleasant enough, it's not a five star hotel but then you don't expect that from a very cheap youth hostel in London.More
