Better to book directly with the owner, and or property website otherwise Homeaway will charge you a "service fee" like 60 plus dollars that don't provide any service and will just direct you to the owner anyway for all your questions
Their guarantees don't mean anything
Watch out for properties that are considered external bookings, which by the way you will never know till your hooked and booked that have extra contracts to sign and make sure you read and understand every term in there. Homeaway will never help you and basically their customer service is useless.
Be careful,
