Generator Hostel London

It is one of the most popular hostels in London because the prices are good and it has what is perhaps the cheapest bar in town. It is a mega hostel with 800 beds with a starting price of 15 pounds (18 €) which includes a buffet breakfast. They make their money mainly from the pub / restaurant, where your can have breakfast, lunch, and dinner a la carte. It's pretty loud, so I'd suggest using ear plugs for those who are not very nocturnal.
