It's, without any doubt, the best Hostel I've ever been to!
The only thing I can complain was the cleanliness, the floor in the bedroom was dirty (hair, etc), and same thing for the showers and the toilets floor. But the rest was great! Good point for the little breads for breakfast.
the staff was very nice, welcoming and helpful. the bedroom was clean and clear, as the bathroom. maybe not enough places in the kitchen but we can't change its size. anyway, a very good hostel, near supermarket, bank and underground and lots of bus lines which go to the main places of London.
