If you are truly looking for savings, this Hostelz.com specializes in low-cost lodgings, canvassing the likes of Hostelworld, Hostelbookers, Gomio, and Hostelsclub. Since it focuses exclusively on budget accommodations—hostels, guest houses, university dorms, B&Bs, campgrounds, some apartments—it is low on our list when it comes to the volume of properties that surface. Its budget niche means it just can’t beat the others there. Surprisingly, however, Hostelz.com still beat Trivago (by a lot) in the number of rooms found for under $75 in Rome, and trounced Kayak in the number of Hong Kong lodgings in the budget brackets. What’s more, the site beat everyone on finding Boston lodgings under $125. In fact, no other search engine came up with anything under $75 in Boston, but Hostelz.com found four options, including a cool clipper ship from $60. It didn’t rank higher because it excludes so many properties, so if your budget goes beyond $80, look elsewhere, but if hostel life or oddball budget lodgings are your style, this meta-search engine is worth checking.
