During my recent stay at The Inn at Penn, I had a very disappointing experience. After being stuck in the airport for five hours, I was too exhausted to inspect the pillows closely and slept on the softest of the four provided. The next morning, I discovered two large, disturbing stains on the pillowcase — dry, but possibly blood. I felt awful realizing I had slept on a pillow in that condition. Cleanliness is a basic expectation, especially at a hotel of this standard, and I cannot believe housekeeping overlooked something so obvious when preparing the room.
