Really good hostel experience! It's very cheap and the location is really good - nearby you can find St Pauls Cathedral, an information office and the millennium bridge. You can pick buses almost everywhere and there's a subway entrance superclose to the hostel, right in front of the cathedral. There are a lot of restaurants nearby and if you prefer to buy food at a supermarket, you've got Salisbury and Marks n Spencer really close. (tip: wait to buy your dinner till salisbury is about to close, at 11pm, 'cos they'll lower their prices like crazy - i bought a bag of quality food for about 4 pounds!).
Regarding the hostel, it was nice and clean. However, the rooms were very small - i didn't mind that 'cos i was travelling with friends, but anyway sometimes it was hard to walk around. The beds are kind of... one on top of each other! but they are comfy, i slept really well and heard no noises from the street or other rooms. There are small but very deep lockers where you can put all your things - but bring your own padlock. The bathrooms are clean but shared (the rooms only have a sink and a mirror). That means that you have to walk around a bit to have a shower or go to the toilet, 'cos sometimes the closest ones to your room are occupied. That can be a bit annoying...
The hostel offers breakfast for 5 pounds - i took it a couple of days and it's worth it, varied and tasty. There was a bad thing: the stairs. I stayed at the second floor and the stairway was kinda old and steep, I kept on tripping and got very tired every time I had to go up!
To sum up, it's a very nice hostel if you're not looking for luxuries and you're going to spend all the day outside (as we did).
