Smart Pricing doesn't work well for the area that we operate in - it is certainly skewed in the favour of guests, and can easily become a driver to a downward spiral in prices. My concern would be a scenario where prices are potentially driven lower and lower each season and across each AirBNB. If your price on smart-pricing is "x", will smart-pricing recommend your neighbour drops to "x - 10" to increase their occupancy, and then cycle back to your accommodation and recommend "x - 15" to build your occupancy.
On a practical level, smart-pricing has often recommended prices for our apartment that just don't make our apartment viable. The goal of smart-pricing seems to be to build occupancy (i.e. more guests use AirBNB), not to necessarily build your overall revenue (less guests but at a higher rate). I would rather achieve revenue from fewer guests, than run very full at a lower rate - less costs related to wear-and-tear.
