HotelTonight sings last-minute booking from the mountaintops

The founders of HotelTonight must have fancied an alpine ski vacation this winter, because today the popular app announced that is now available in Germany and Switzerland.

HotelTonight is a last-minute hotel booking app that connects travelers with available accommodation from their mobile phones. It is now available in 10 countries and over 80 destinations around the world. It also announced that it surpassed 4 million downloads.

Each day at noon local time, HotelTonight offers a new set of deals. If you find yourself without a place to stay in a strange city, simply launch the app and select the city, and it will present you with unsold rooms at steep discounts. Travelers can book the deal through their smart phones, and in no time at all, be staying comfort.

HotelTonight opened its doors in January 2011 and raised $23 million last June to promote global expansion. The San Francisco-based company has a strong U.S. presence and recently opened its European headquarters. In addition to Belgium, France, Ireland, the Netherlands, and the U.K., it is now active in Berlin, Munich, Zurich, and Geneva.

HotelTonight has also been busy updating the product. The 4.0 version of the iOS and Android apps debuted in September to provide travelers with more personalized recommendations based on their exact location, booking history, and feedback. These efforts have not gone unrecognized by users, venture capitalists, or the tech community. Apple named HotelTonight one of the most disruptive services of the year, and it received a Best E-Commerce Application nomination for the 2012 Crunchies Awards.
