Cancellations

[Joan157]

For the first time, this year we have had 3 cancelations.  One date, we had to tell another guest that time was booked.  Now original guest cancels 1 month before reserved date!  

Are guests now treating reservations like Booking.com which has free cancelations?  A place sounds like fun, they book knowing they can cancel a month ahead?  If so, how can we stop this?  I'd like a no refund policy.  Presently, we not only lose income, but it messes us up with our cleaner.
