Instead of focusing on occupancy rates, focus on researching your market, so you're familiar with market rents. Then like any product or service, price it so other people will be attracted to your unit. As a rental, make it the best unit in the price range, and your unit will likely stay rented.
Weekly rentals will fall into the category of vacation rentals, so that would be a different market completely.
