Ghosted!
I arrived at St John and expected to receive final address and access information. I tried messaging the owner, then finally tried having VRBO contact the owner. No reply. So there I was at 5 pm hustling to find and place to stay.
Until I hear from the owner, with a plausible excuse, my recommendation is to avoid this accommodation, or you might find yourself also in my position, last minute scrambling for a place to stay.
