Do not live at property location so I cannot "confirm it"
I recently bought a condo in Kauai Hawaii. It is a vacation rental and I do not live there, but will go there several times a year. I would like to list on Booking.com and created the property in my account. However, I will not be there to receive the letter. I saw in the documentation to "contact support" in this situation for other ways to verify ownership, but I can find now way to contact them.
