Found 2 reports:

We stayed here last week in September 2012, last day I woke up itching. Looked down on the stark white sheets to see a bug filled with my blood crawling around on the sheet.

I stayed in April 23 - 27 and I got Bed Bugs after that stay. I filed a report with the hotel, they said that they would look into it.
