"Hint: You've stayed here before ;)" - on Priceline Express

[WillTravel]

I was searching for my October Portland stay (I was trying various days, and I'm not sure what date this came up with), and I saw a Priceline Express for a 3* Downtown hotel with the text "Hint: You've stayed here before ;) ". That told me it was the Marriott Courtyard, as I think that's the only 3* Downtown hotel I've stayed at with Priceline. 

I've been trying searches since, and I have not seen the message again. Has anyone else seen that?
