Before I went to Madrid two weeks ago, I took a chance on Priceline and bid $75 for a 5 star hotel. I got rooms at the Hesperia Madrid, which were gorgeous and the mattress was to die for. We stayed in the Castellana District, which is why we got that room for that price. I have never slept in a more comfortable bed, and I am a 5'11 female. So long as you stick with a 5 ***** bid, I don't think you can go wrong.
