I am going to try to reserve a room at either Hostal Martin , or Hostal Cervantes , both in Madrid. I went to their websites and cliked on "Reservations." There was a page you fill out, except, they did not ask for a credit card number? Are they really going to hold a room without my credit card info? Anybody ever reserved through this type of system before and had success?? Thanks

Hi! I just made a reservation at Hostal Cervelo using email. In their first email reply they confirmed room availability for the dates I wanted (in August), and they asked for my credit card information by reply to reserve the room. I'm glad they have AC, cuz it's sure to be HOT in August!
