Carol, we used BSV arrangement for testing this past November. It was very simple and convenient. You tell Viki (the manager) when you need test done, he calls nurse and ask if she is available, arranges time and day. She comes to your villa, takes about 10 minutes from start to finish, gives you paper with results, $60 cash or credit card. You will receive email with results later in a day also. She came to our unit 3 times as we had people in our party coming and going different times and everything went smoothly. Would use her again.
