Hostel Bookers
HostelBookers is a hostel search engine that lets travelers book budget accommodation in more than 3,500 destinations worldwide. The website is simple to use: simply type in your destination, hit Search, and you’ll be presented with a list of hostels. You can choose to filter by price, rating, amenities, room types, and more.
One of the best features is that you can see how much a bed in a dorm and a private room would cost without having to click on the actual hostel page. The website will also alert you when a specific hostel has a sale, so that you can get the best deal every time.
