Hello - I found a set of keys in the street (Portland OR) that has a tag that says Carriage House, and a blue tag that says Anameara Guest. I Googled "Carriage House Portland Oregon" and found 2 AirBnB listings. The system is not allowing me to send a message to the host unless I choose dates on the calendar related to a stay but I am just trying to send a message about the keys. Is there a way to do that?
