Normally we have a great experience with Doubletree. This time, however was different. After waiying over half an hour at check in, we finally were able to make it to our room. When we torned down the bed, there were blood stains on the sheets. When we called the front desk, they said they were sending someone up. 20 minutes later, someone arrived, handed us a stack of sheets and when we offered to show them the stains, we were told "I just drop off the sheets..." and he left.
