Found a long hair under my pillow and two small red (dried blood) spots on the cover sheet of which I also took photos. Can't imagine not changing sheets, which even worse during Covid. I made sure to wash all my travel clothes after in case there were bed bugs. Told the front desk employee, they kept saying 'not to worry' and he'll let the manager know. He said they don't have bed bugs because of the type of sheet covers they use. That's a red herring since the cover didn't seal the mattress and they can also be found hiding in wood furniture. No apologies or follow up from them.
