Brilliant way to search and book accommodation online
I always use HostelBookers while travelling to browse and book hostels online. It is cheaper than Hostel World as there is no booking fee, I've never had any problems using it as a third party to book, upon arriving at the place i'm staying. It's handy because you can filter your searches, view as a list or map view, and various other features that make it easy to hunt for a place to stay, whatever your need. I've even managed to use it to book on intermittent wifi on my iphone with no problems.
