Anyone seen a bump in their STR returns by improving curb appeal?

[Jon Martin]

Assuming that your interior, furnishings, amenities, location, management, etc are dialed in and high quality, but the exterior is average in appearance, boring and dated.  

Have you seen a bump in bookings  with cosmetic exterior upgrades like updated siding, decorative lumber to front porch rails/bannisters, nice front door etc that would allow you to feature that photo in your listing?
