Located right at London Bridge and a 10 minute walk to Tower Bridge, you can't beat the location. There are large cages under the bed that hold all of your stuff. The staff seemed friendly enough. Laundry isn't available before 4pm, so don't plan on doing it before then. Clean hostel. Not many outlets in the room though, so bring an extension cord.
This "hostel" was the cleanest one I've ever stayed in- it was more like a hotel. The all you can eat breakfast (an additional 6 euros) was definitely worth it. It's also very family friendly. The bar offered some good drink deals. The one complaint I have is that we couldn't get our room until 2 hours after the official check in time. The staff originally told us it would only be a half hour wait, but then they kept extending that wait and it was very frustrating.
