i'm lookin at 3,4,5 star hotels in frankfurt germany from 3/17/11 to 3/20/11. i see several hotels with 3 or 4 red stars, but the written description has them at 4 or 5 stars. an example of this would be the sheraton frankfurt airport hotel & conference center. it has 4 red stars next to the price, but the written description has it as a modern 5 star hotel. when bidding, would this be a 4 or 5 star hotel ?
