London Backpackers was very clean and delivered everything it promised. Lovely, private curtains on each of the beds and locks under the beds for valuables. A bit out of the city, but very very close to trains. Awesome experience all around.
One of the best hostel experiences I've ever had. It felt more like a hotel actually. Friendly and open and the staff were impeccable. I would immediately recommend this to a female friend staying in Amsterdam. The location was a bit difficult to locate at first, but after that everything exceeded my expectations.
The Flying Pig was much too far out of the city with no added features for the travel.
