I have already a booking.com account with 2 apartments in the same building.
Now I got another apartment in the same city but a different location. I am logged in into my my admin.booking.com account.
At the top at the right hand site I see "Account", I click to account, the menu is opening and I see at the bottom of the menu:
+ add a new property
+ add existing propertys
It is unclear for me which one I have to choose
Thanks in advance.
