terrible location if youre not coming from the airport in the shuttle. no clear signage of address

The location was under construction. The gates were locked so I had to go around them and climb through the construction site. This was my first time at this location. it did NOT look like a rental agency. I dropped it off at night. Felt I left it in an insecure place - outside the fence. Then I climbed the embankment to walk over to the key drop off. Everything was dark. Good thing I knew where to look and that a friend was close by.
