I've used Prontohotel.com several times to make hotel reservations. Every time, I felt like I got the best deal out there (the first time I even checked against other sites to make sure). I also save a lot of time by using their service because it means that I don't have to go to all of the big-name sites myself. It does it instead. I've always been happy with my hotel choice once I arrive on site and find that, for the most part, the hotels are accurately represented on the site. Nicely done. I'll keep going back for sure!
