Exact arrival times are always a bit dicey when it comes to coordinating flight arrivals, taxis and traffic congestion, but Graciela was quite patient with it all and greeted us in the delightful apartment. And at the end of our stay, she was even more patient as I screwed up and left with a set of apartment keys in my pocket. Fortunately, we were only going to Mendoza and not back to the states, so I was able to express mail them back to BA. I am sure dealing with the traveling public can try one's soul, so I appreciate her even more.
