Maid knocked on door at9:00 am as we were dressing. We left for day at 10:00 am. When we returned at 4:30, room had not been cleaned, bed made or fresh towels provided. We did call and received towels quickly, but for a Hilton to not clean a room is a bit off. Also thin torn shower curtain with no liner that did not even cover full rod. So water all over the floor. I expect more from a Hilton.
