TA is a data site. It does not do any travel agency work. Contacting TA about anything you're interested in is pointless. What TA has done, is to respond to your enquiry giving you the management name of Ana Renkow. This is the name that you will find on the vacation rental page. It is she to whom you must enquire as she will be the manager of the property. Those vacation rentals, holiday rentals places just advertise their properties on TA.
And further to what Hans_DEN has said, we are not TA Staff, but volunteers who go on to any of the forums on TA to offer suggestions, advice, help etc.
Now you have come to the correct forum "Support" to get help with your question. And that help says above to click on the "email owner" (usually an orange button) right on the page for the vacation rental. That will send a message directly to the person you would be dealing with if arranging a stay at the property.
And just a heads up. There have been several posts here on Support from people who have contacted the manager of a vacation rental property to say that they have had no answer, even after contacting the manager 2, 3, 4 times. Once again, that is not the fault of TA, it is directly the fault of the personnel at the vacation rental property. IMO vacation rentals can be a minefield. I would suggest you have a look at vrbo.com for very reliable listings and satisfied customers.
