I had trouble getting in as the instructions to the Realtor Lock Box, although clear were ineffective as it was apparently frozen, This I heard from another guest. At the time, I tried to contact Luis but never heard from him the whole time I was his paying guest of five days. I eventually found a key for the front door stashed in another "Black Box" that was beside the front door. I was never told to look in this box for the key but only to open and reset the combo on the locked-up Realtor style box on the right-hand column. This lock box was un-openable. I'd have thought Luis would have updated the entry instructions.
