The company began testing hotel prediction algorithms back in October 2017, but only in New York. At the time, Hopper CEO Frederic Lalonde explained how online hotel booking differed from airfare. With plane tickets, people are usually just in search of the best price. But with hotels, other factors come into play.

That’s why the new feature lets travelers narrow searches not only by city, but also by neighborhood and points of interest. Hotels can additionally be filtered by the neighborhood, rating, price and their amenities.
