Publove @ The Steam Engine,Waterloo

Plus: The location of the hostel was great! My first night there, I walked into town to see the London Eye, Parliament/Big Ben, and Westminster Abbey. Then, I walked back. Round trip: 1 h, 30 mins. The hostel is also close to a Tube station, so getting anywhere is a breeze. Staff were friendly, price was good, and there was a good mix of travellers.

Minus: Close to a major road, so you get a lot of noise :( Only two showers and two toilets between approx. 25 people. I'm actually quite surprised it wasn't too much of an issue. Bathrooms could have been a bit cleaner.
