We are in our villa at the moment, and have had two packages delivered by UPS. Both packages had a tracking number, but when I logged on I wasn't able to track it. I didn't try too hard, as we were going to be out most days. With both packages they were left in our post box by the roadside, and not on the porch. However, if it was a larger package they would have left it in our porch.

You might like to check with the villa owner, to see if there is a porch that can be used to safely leave packages, or they may have a post box by the side of the road.
