The staff was nice, and the guests seemed nice too. I also liked the common room/ kitchen a lot; it was cosy, well decorated, and had space for everything (eating, connecting, watching TV, etc). I didn´t like my room though: it was too small and with no windows. Another bad point was location: it´s on Zone 3, so bad for signtseeing or if you want to be close to the city centre for some reason. A good point, however, is that some guests can pay their stay by working there.
I stayed at one of the LU rooms. As adviced by the hostel, they are small, noisy, but quiet (yes, both at the same time, since they are very quiet, except when the underground passes near you :)). So not exactly a suite, but this hostel had many other good points: the bathroom facilities, the common room (mixture between living room, pub & Internet cafe), & the staff (really helpful and nice). It's also cosy & safe. The breakfast however, was very poor; and you had to wash your dishes yourself!
It was a nice place to spend a week, and the best place in London value-prize wise. The area was also nice and safe. However, the atmosphere at the Hostel was not always the best. For example, some people were noisy at nights, and there was nobody around 24h to call their attention and avoid disturbances. Also, it was less of a Hotel and more of a big shared house, which helped creating a family environment.
