Best of luck to you.
Hope it works out.
Having had a successful rental directly through them in the past I'm sure helped ease any misgivings about booking directly in the future. However, using a go-between, if you will, places all of what you are going through on thier shoulders as your advocate with the villa owners.
This Playa.Info site is THE place to book your future villa/condo rentals as they have access to MUCH more property-wise than has been updated on the list in the Trip Planning Tab and the Villas section.
