We are always available for both our users and their guests!
Generally, except for in emergency situations, the best way for guests to contact us is by simply sending a message on Airbnb or by emailing firstname.lastname@example.org. Both options are monitored 24/7.
In case of emergencies, we can be reached at (415) 992-7692.
As a startup our ability to handle many calls is limited so please advise your guests to use the textual option first.
