I gave it a 3 because of the way you "bid" on rooms, car rental, etc. I've won a couple of good bids but I don't like the way you pick your price but you can't request a certain area around town. I booked my husband in Detroit and even though I ask for at least 3 stars, the room he got was in downtown Detroit between the airport and highway... very noisy for the price. Just be careful.
