Make sure to reach out the day of check in to receive a code to enter the house. We were sent an itinerary the day of and I assumed there was a code included in there bc I notice that check in was through a lock box. By the time we checked in it was really late and after the check in hours bc our flight was delayed and we still had to pick up our car rental. Thankfully though after 15 mins locked outside we finally got through to Alba on the Airbnb messenger app.
