Your apartment has a fabulous view and is quite nice, @Alice229. Good question and there are several considerations. First, is your listing in an area where there would be many business travelers? Unlike vacation guests, business guests are not as dependent on weather being good. Second, are you willing to be a landlord (not a host) as the long term guest is a different type of experience.
Take advantage of the Help Center and look up articles about business travel as qualifying could be a great source of reservations for you. Also, look up long term reservation articles which describe the cancellation and payout processes that are different from short term hosting.
Finally, on this site under Discuss check into the Home Sharing Club section. There is a Vancouver club and it's members should be able to educate you about the seasonality of your listing area.
Good luck and congratulations on your graduation!
